Quantum Satellite
For Prelims: Quantum satellite, Quantum Physics, Encryption, Quantum Entanglement, India, Make in India, Skill India, International Telecommunication Union
For Mains: National Quantum Mission, Quantum Technologies and their Implications
Why in News?
India’s National Quantum Mission (NQM) aims to launch a quantum satellite in 2-3 years, advancing secure communications through quantum physics. This initiative positions India at the forefront of next-gen technology.
What is a Quantum Satellite?
- About: A quantum satellite is a communications satellite that employs quantum physics to secure its signals, making it highly resistant to interception.
- It utilizes quantum cryptography (a method that uses quantum mechanics to encrypt and transmit data), particularly Quantum Key Distribution (QKD), to protect data by detecting eavesdropping during transmission.
- Quantum Cryptography:
- Encryption Basics: Classical encryption methods, like the Caesar cipher, messages are encoded in a secret code. Without the key, it is not possible for eavesdroppers to decipher the message.
- However, these methods are vulnerable to quantum computers, which could crack the code much faster than traditional supercomputers.
- Quantum Encryption: It uses quantum key distribution (QKD), to secure messages.
- In Quantum Measurement, when a quantum system, such as a photon (a tiny particle of light), is measured, its state changes.
- If an eavesdropper attempts to measure the photons carrying a key, this interference alters the state of the photons. As a result, the legitimate parties communicating will immediately detect that the key has been compromised.
- Additionally, quantum entanglement ensures that any change to one photon instantly affects the other, making it impossible for an eavesdropper to alter the information without detection.
- This makes QKD offer "unconditional security" by detecting any interception, ensuring secure communication.
- In Quantum Measurement, when a quantum system, such as a photon (a tiny particle of light), is measured, its state changes.
- Encryption Basics: Classical encryption methods, like the Caesar cipher, messages are encoded in a secret code. Without the key, it is not possible for eavesdroppers to decipher the message.
- Global Developments in QKD: China currently operates the world’s largest QKD network, which includes three quantum satellites and four ground stations.
- India is advancing its quantum communications experiments, with plans for a satellite-based QKD network. Studies by the Raman Research Institute, Bengaluru, suggest that the Indian Astronomical Observatory in Hanle, Ladakh, offers ideal conditions for such a system.
- Indian Space Research Organisation (ISRO) has successfully demonstrated free-space Quantum Communication over a distance of 300 m.
- The United Nations (UN) has designated the year 2025 as the ‘International Year of Quantum Science and Technology’ to increase public awareness of the importance of quantum science and its applications.
- India is advancing its quantum communications experiments, with plans for a satellite-based QKD network. Studies by the Raman Research Institute, Bengaluru, suggest that the Indian Astronomical Observatory in Hanle, Ladakh, offers ideal conditions for such a system.
What are the Limitations of Quantum Key Distribution?
- Technological Maturity: The technology is still in the experimental phase in India, and commercial implementation of large-scale QKD networks is not yet feasible.
- Infrastructure Costs: Implementing QKD requires specialized hardware and infrastructure, which increases costs compared to traditional cryptography methods.
- Integration: Integrating QKD with existing communication networks and ensuring compatibility with classical encryption systems presents a significant technical challenge.
- Lack of Authentication: QKD doesn’t provide a reliable means to authenticate the source of the transmission, making it vulnerable to potential attacks where an adversary could impersonate a legitimate party.
What is the National Quantum Mission (NQM)?
- About: The NQM, launched in 2023 with a Rs. 60,000 crore investment from 2023-24 to 2030-31, aims to advance Quantum Technologies in India and position India as a global leader in Quantum Technologies and Applications (QTA).
- Objective: The NQM aims to develop quantum computers (build intermediate-scale quantum computers with 50-1000 physical qubits (quantum bits) over 8 years), utilizing superconducting and photonic platforms.
- It will establish satellite-based secure quantum communications within 2000 km in India and internationally.
- The NQM will support inter-city quantum key distribution over 2000 km and develop multi-node quantum networks. It also focuses on creating atomic clocks for precision applications.
- Significance: NQM aims to make India a global leader in quantum technologies, surpassing classical physics limits with advanced capabilities beyond current systems.
- National Priorities: The NQM aligns with and supports national priorities like Digital India, Make in India, Skill India, Start-up India, and Self-reliant India.
- Implementation: The Mission will establish four Thematic Hubs in collaboration with top academic and National R&D institutes. These hubs will focus on Quantum Computing, Quantum Communication, Quantum Sensing & Metrology, and Quantum Materials & Devices.
- These hubs will drive new knowledge and research, advancing quantum technology.
- Sectoral Impact: The Mission will greatly benefit sectors such as communication, health, financial services, energy, and more. Specific applications include Drug design, Space exploration, and Banking and security.
Way Forward
- Post-Quantum Cryptography: Due to limitations of QKD, some experts recommend using post-quantum cryptography, which combines quantum-resistant algorithms with classical encryption techniques, offering an alternative to the hardware limitations of QKD.
- Quantum Authentication: Creation of quantum authentication protocols that ensure both encryption and identity verification will be key. This will close the gap in the security chain and make the system resistant to impersonation and data breaches.
- Miniaturisation and Robustness: Developing smaller, energy-efficient, and cost-effective quantum devices for scalable deployments will make the technology accessible across industries like defense and healthcare.
- International Collaboration: Global cooperation is crucial for a standardised and interoperable quantum communication network. India should influence international standards and, through platforms like the International Telecommunication Union (ITU), ensure its quantum systems are interoperable and meet global security requirements.

Dark Matter and Dark Energy
For Prelims: Dark Matter, Electromagnetic Force, Protons, Neutrons, Electrons, Weakly Interacting Massive Particles, Neutrino, Black Hole, White Dwarfs, Neutron Stars, Brown Dwarfs, Gravitational Lensing, IceCube Neutrino Observatory, Large Hadron Collider, James Webb Space Telescope, Dark Energy.
For Mains: Dark Matter and Dark Energy
Why in News?
Recently, physicists revised the minimum mass of dark matter and pushed it up to 2.3 × 10-30 proton masses.
- For decades scientists thought this minimum mass was about 10-31 times the mass of a proton.
Note: In 1922, Dutch astronomer Jacobus Kapteyn concluded the density of “dark matter” (using that term for one of the first times) must be 0.0003 solar masses per cubic light year.
What is Dark Matter?
- About: Dark matter is a form of matter that is entirely invisible, emitting no light or energy, making it undetectable by conventional sensors and detectors.
- Dark matter doesn't interact with electromagnetic forces, so it neither absorbs, reflects, nor emits light, making it hard to detect.
- Dark matter makes up about 27% of the universe, outweighing visible matter six to one, while visible matter accounts for only 5%.
- Visible matter (Baryonic matter) consists of subatomic particles like protons, neutrons, and electrons.
- Composition of Dark Matter: Dark matter is thought to consist of non-baryonic WIMPs (weakly interacting massive particles), 10-100 times the mass of a proton, but weakly interacts with normal matter, making detection difficult. Among WIMPs are:
- Neutralinos: They are hypothetical particles (not yet been observed) that are heavier and slower than neutrinos.
- Sterile Neutrinos: Sterile neutrino is proposed as a dark matter candidate as it only interacts with regular matter through gravity. Also, neutrinos are particles that don't form regular matter.
- Origin of Dark Matter:
- Big Bang Theory: Dark matter may have formed during the Big Bang and concentrated into black holes, where their gravitational forces trap dark matter particles.
- Stellar Remnants: Stellar remnants such as white dwarfs and neutron stars are also thought to contain high amounts of dark matter.
- Brown dwarfs (failed stars) that didn't accumulate enough material to kick-start nuclear fusion in their cores can also be a source of dark matters.
- Evidence of Dark Matter:
- Galaxy Rotation Curves: According to Newtonian gravity, objects at the edge of galaxies should be moving slower than those near the center.
- Observations show stars on galaxy edges move faster than expected, suggesting unseen mass—attributed to dark matter—provides extra gravitational pull.
- Gravitational Lensing: Gravitational lensing occurs when light is bent by a massive object's gravity, revealing more mass than visible, suggesting the presence of dark matter.
- Galaxy Formation: Galaxies' distribution and motion over time suggest dark matter, as it enables galaxies to clump together and form current structures.
- Galaxy Rotation Curves: According to Newtonian gravity, objects at the edge of galaxies should be moving slower than those near the center.
- Projects to Study Dark Matter: There are some key projects designed to shed light on dark matter.
- Alpha Magnetic Spectrometer (AMS): The AMS is an experiment mounted on the International Space Station which has detected an excess of positrons (the antimatter counterpart to electrons), which may be a signature of dark matter.
- XENON1T: The XENON1T experiment in the Italian Gran Sasso Laboratory aims to detect dark matter by observing the interactions of WIMPs with xenon atoms.
- IceCube Neutrino Observatory, Antarctica: The IceCube Neutrino Observatory is investigating the possibility of sterile neutrinos—hypothetical particles that only interact with regular matter via gravity and could be a form of dark matter.
- Particle Colliders at CERN, Switzerland: CERN's Large Hadron Collider (LHC) conducts high-energy particle collisions to probe the fundamental particles of the universe. The LHC also looks for potential signs of dark matter by analyzing the aftermath of particle collisions.
- James Webb Space Telescope (JWST): JWST is expected to provide valuable insights into how galaxies and cosmic structures developed, which could help us understand the role of dark matter in their formation.
Note: Antimatter consists of particles that are essentially the same as visible matter particles but with opposite electrical charges.
- These particles are called antiprotons and positrons (or antielectrons).
- Antimatter is not the same as dark matter.
What is Dark Energy?
- Dark energy is a mysterious form of energy that makes up about 68% of the universe. It is thought to be responsible for the accelerated expansion of the universe.
- It is distributed evenly throughout the universe, not only in space but also in time i.e., its effect is not diluted as the universe expands.
- The even distribution means that dark energy does not have any local gravitational effects, but rather a global effect on the universe as a whole.
- This leads to a repulsive force, which tends to accelerate the expansion of the universe.
- The rate of expansion and its acceleration can be measured by observations based on the Hubble law.
- Hubble's Law states that galaxies move faster away from Earth as they are farther, implying the universe is expanding.
Conclusion
Dark matter, making up a significant portion of the universe, remains elusive yet crucial for understanding cosmic structures and evolution. Ongoing experiments and astronomical observations continue to explore its properties, origin, and impact, promising advancements in fundamental physics.

Ocean Anoxic Event 1a
For Prelims: Anoxic Marine Basins, Carbon sequestration, Holocene extinction, Ocean acidification, Coral Reef, Paris Agreement
For Mains: Earth's mass extinctions, Impact of volcanic eruptions on climate and ecosystems
Why in News?
A recent study, published in Science Advances, has provided new insights into the timing and duration of Ocean Anoxic Event 1a (OAE 1a).
- By studying prehistoric rocks and fossils from Mount Ashibetsu, Japan, researchers have pinpointed the causes and timeline of the OAE 1a that caused widespread oxygen depletion (anoxic) in Earth's oceans.
What is the Ocean Anoxic Event 1a?
- Definition: OAE 1a refers to a period during the Cretaceous Period (145 million years ago and ended 66 million years ago) when Earth's oceans became depleted of oxygen, causing a significant disruption in marine life.
- Cause: The event is believed to have been triggered by massive volcanic eruptions that released significant amounts of carbon dioxide (COâ‚‚), leading to global warming and oxygen depletion in the oceans, which subsequently resulted in the formation of anoxic marine basins.
- Impact: CO2 in seawater forms carbonic acid, dissolving sea creatures' shells and lowering oxygen levels.
- This oxygen depletion led to the extinction of marine species, particularly plankton, and caused the formation of organic carbon-rich layers known as black shales.
Anoxic Marine Basins
- About: An anoxic basin is a body of water, typically found in deep ocean regions, where oxygen levels are extremely low or absent.
- This lack of oxygen prevents the survival of most aerobic organisms, but allows specialized microbes and certain fungi to thrive.
- These conditions are often associated with deep-sea areas or lakes that are isolated from the oxygen-rich surface water.
- Carbon sequestration: Anoxic basins slow the decay of organic material (due to low oxygen), preserving carbon. This makes them potential sites for long-term carbon sequestration, helping reduce COâ‚‚ levels in the atmosphere.
- Examples: Black Sea, Cariaco Basin (Caribbean Sea), and Orca Basin (northwest Gulf of Mexico).
- Dead Zones: These are hypoxic areas (low oxygen) in oceans and large lakes where oxygen levels are too low to support most marine life.
What are the Key Highlights of the Study on Ocean Anoxic Event 1a?
- Timing of OAE 1a: The study pinpointed the exact timing of OAE 1a to around 119.5 million years ago, using advanced isotopic analysis of volcanic tuffs (igneous rocks formed from the compaction and cementation of volcanic ash) from Japan’s Hokkaido Island.
- OAE 1a lasted 1.1 million years, revealing how long oceans took to recover from CO2-driven warming and anoxia.
- Volcanic Eruptions: The study confirmed that volcanic eruptions released CO2, triggering oceanic oxygen depletion.
- Relevance to Modern Climate Change: The study links past volcanic COâ‚‚ emissions to current human-induced warming, warning that the rapid pace of modern warming could trigger similar disruptions and potentially lead to a Holocene extinction (probably a sixth mass extinction event).
- It also highlights the long-term impact of elevated CO2 on marine ecosystems and the global carbon cycle.
What are the Major Mass Extinction Events on Earth?
- Ordovician-Silurian Mass Extinction (443 million years ago):
- Impact: Wiped out approximately 85% of all species.
- Cause: Dramatic temperature drop and glaciation, leading to sea level fall, followed by rapid warming.
- Devonian Mass Extinction: Occurred 374 million years ago:
- Impact: Killed about three-quarters of Earth's species, mostly marine invertebrates.
- Cause: Environmental changes such as global warming, and cooling, fluctuating sea levels, and reduced atmospheric oxygen and carbon dioxide. Exact triggers of the extinction remain unclear.
- Permian Mass Extinction (250 million years ago):
- Impact: Known as "The Great Dying," it eradicated over 95% of species, including most vertebrates.
- Cause: It is linked to massive volcanic eruptions in the Siberian Traps, Russia, causing global warming and ocean anoxia. Volcanism, climate shifts, and a potential asteroid impact likely exacerbated the catastrophe.
- Triassic Mass Extinction (200 million years ago):
- Impact: Eliminated about 80% of species, including many dinosaurs.
- Cause: Extensive geological activity that raised carbon dioxide levels, global temperatures, and caused ocean acidification.
- Cretaceous Mass Extinction (66 million years ago):
- Impact: Killed 78% of species, including non-avian dinosaurs.
- Cause: Likely caused by an asteroid impact in Mexico, creating a massive crater, global cooling, and ecosystem collapse.
- Additionally, volcanic eruptions in India's Deccan Plateau may have worsened the event by contributing to global warming.
What is the Holocene Extinction?
- About: The Holocene Extinction, also known as the Sixth Mass Extinction, refers to the ongoing extinction event that began around 12,000 years ago and is largely attributed to human activities, unlike previous mass extinctions, which were caused by natural phenomena.
- Key Drivers:
- Overexploitation: Overharvesting resources like overfishing, hunting, and poaching depletes species.
- Habitat Loss: Conversion of land for agriculture and urbanization reduces habitats and fragments populations.
- Climate Change: Human-induced climate shifts disrupt ecosystems, species distribution, and relationships.
- Pollution: Industrial, agricultural, and waste pollution harms ecosystems through chemicals and plastics.
- Invasive Species: Non-native species disrupt native ecosystems, outcompeting or preying on local species.
- Key Examples of Holocene Extinction Events:
- The Megafauna Extinction (12,000 years ago) wiped out large mammals like mammoths and saber-toothed cats, likely due to human hunting and climate change.
- Coral Reef Bleaching is driven by rising sea temperatures and ocean acidification, endangering reef biodiversity.
- Amphibian Declines, especially frogs, are caused by habitat loss, pollution, and diseases like chytridiomycosis.
- Impact: The current extinction rate is 1,000-10,000 times higher than natural rates.
- Ecosystem services, such as food production, clean water, and air, are at risk, threatening both biodiversity and human life.
- Efforts to Mitigate the Holocene Extinction: Strengthen commitments to cut carbon emissions and limit global warming to 1.5°C, as outlined in the Paris Agreement.
- Collaborate globally to conserve at least 30% of lands, inland waters, and oceans, as under the 30X30 Initiative.
- Encourage individuals, businesses, and communities to adopt sustainable practices and demand accountability from governments and corporations.

Conservation of Cephalopods
Why in News?
Recently, California and Washington have approved bans on octopus farming. Hawaii is considering similar action against raising octopus, a member of Cephalopods, demand for food.
What are Cephalopods?
- About: Cephalopods are a class of ocean-dwelling intelligent invertebrates that includes cuttlefish, squid and octopus.
- Cephalopods are a broad class of molluscs. Mollusca are soft-bodied invertebrates, often enclosed partly or fully in a calcium carbonate shell.
- Early cephalopods had protective shells, but many lost them, and evolved traits like high intelligence, flexible arms, and camouflage.
- Diversity: Cephalopods are a diverse class with three superorders:
- Octopodiforms (octopuses and related species)
- Decapodiforms (squid, cuttlefish, and related species)
- Nautiloids (nautiluses and related species)
- Anatomy: The term cephalopod means "head foot," referring to the connection between their head and arms.
- Cephalopods have two eyes and at least eight arms. E.g., octopuses are eight-armed while squids are ten-armed.
- Nautiluses are the only cephalopods with an external shell.
- Eyes and Vision: Most cephalopods are likely colorblind and exhibit visual camouflage.
- They can open and close tiny sacs just below their skin that contain coloured pigments and reflectors, revealing specific colours.
- Movement: Cephalopods mainly use jet propulsion, expelling water from their mantle cavity to propel themselves.
- Octopuses walk with their arms, while squid and cuttlefish use fins for movement.
- Circulatory System: Cephalopods have three hearts: two pump deoxygenated blood, and one pumps oxygenated blood.
- Their blood is blue due to copper-based hemocyanin, which is less efficient than iron-based hemoglobin but highly effective in cold, low-oxygen environments.
- Brain: Over half of the neurons in common octopus (Octopus vulgaris) are not in the brain at all, but distributed in “mini-brains,” or ganglia, in the arms.
- Most neurons in the central brain focus on vision, leaving less than a quarter for learning and memory.

- The Northern giant hornet (Vespa Mandarinia) is the largest hornet (wasp) in the world, measuring up to 2 inches long.
- A wasp is a type of insect belonging to the order Hymenoptera, which also includes bees and ants.
- It has a large, solid yellow or orange head with black eyes.
- It is native to Asia and was first spotted in Washington state near the Canadian border in 2019.
- It poses a significant threat to insects and native pollinators which can kill an entire beehive (bees habitat) of honeybees in just 90 minutes.
- It can even kill people as it delivers seven times more venom than a honey bee and can sting multiple times.
- They usually build their nests in forested areas, often in an underground cavity.
- The Northern giant hornet (Vespa Mandarinia) is the largest hornet (wasp) in the world, measuring up to 2 inches long.

Undersea Cable Network
India is set to launch two new cable systems in the coming months namely India Asia Xpress (IAX) and India Europe Xpress (IEX).
- IAX connects Chennai and Mumbai with Singapore, Thailand and Malaysia in Asia while IEX connects them with France, Greece, Saudi Arabia, Egypt and Djibouti.
- Undersea Cable (Submarine Cables):
- They are high-capacity optic fibre cables laid on the ocean floor that play a crucial role in providing global connectivity for high-speed data exchange.
- Fiber optic cables that use fast-traveling pulses of light to transfer digital information. It relies on total internal reflection for their operation.
- Lasers on one end fire at extremely rapid rates down thin glass fibers to receptors at the other end of the cable.
- These glass fibers are wrapped in layers of plastic (and sometimes steel wire) for protection.
- They provide unlimited bandwidth and very low latency compared to satellite communication which face risks from space weather, radiation, and debris.
- As of 2023, India had 17 international subsea cables landing in 14 distinct stations across five cities, with a cumulative lit capacity of 138.55 terabits per second (tbps) and activated capacity of 111.11 tbps.

Meat- Eating Squirrels
A study led by the University of Wisconsin-Eau Claire (US) has discovered that California ground squirrels (Otospermophilus beecheyi), previously considered herbivores, exhibit opportunistic omnivorous behavior.
- Researchers observed the squirrels hunting, killing, and eating voles (rodents), with 42% of 74 interactions involving active hunting.
- The squirrels' carnivorous behavior peaked in early July, coinciding with a surge in vole numbers, indicating their hunting was triggered by an abundance of prey.
- It revealed that squirrels' diets are more flexible than previously believed, helping them adapt to changes in food availability and survive in rapidly changing environments.
- California Ground Squirrels:
- It is also known as the Beechey ground squirrel and commonly found in western US.
- They have mottled fur, with gray, light and dark brown, and white present in their pelage.
- They are commonly preyed upon by rattlesnakes, eagles, raccoons, foxes, badgers, and weasels and can live up to 6 years in the wild.
- IUCN Red List: Least Concern
- CITES: No special status
- The Indian palm squirrel (Funambulus palmarum) is commonly found in India and Sri Lanka.

Marburg Virus Disease
Rwanda has successfully contained and declared its first-ever Marburg Virus Disease (MVD) outbreak officially over after a 42-day period without new cases.
- MVD is a severe and often fatal hemorrhagic fever caused by the Marburg virus, with high case fatality rates and no approved treatments currently available.
- Transmission: It is transmitted from fruit bats (Rousettus aegyptiacus) to humans, and spreads through direct contact with bodily fluids of infected individuals.
- Symptoms: MVD starts with high fever, severe headache, and malaise.
- As it progresses, it can cause severe bleeding, shock, and multi-organ failure, with death occurring 8-9 days post-symptom onset.
- Diagnosis: Diagnosis is confirmed through tests like RT-PCR (Reverse Transcription Polymerase Chain Reaction), and virus isolation, which require maximum biohazard containment.
- Treatment: No approved vaccine or antiviral treatments; supportive care, such as rehydration and symptom management, improves survival.
- Control: Key control measures include community engagement, safe burials, contact tracing, and infection control in healthcare settings.
- Key Facts About Rwanda: It is a landlocked country in East-Central Africa, known as the "Land of a Thousand Hills." It shares borders with Burundi, Tanzania, Uganda, and the Democratic Republic of the Congo.
- Kigali is the capital. The Nile and Congo rivers flow through Rwanda.
