On World Quantum Day (14^th  April), Bengaluru-based QpiAI launched India’s first full-stack quantum computer, QpiAI-Indus, a major milestone in the country's National Quantum Mission (NQM). 

QpiAI-Indus 

• About: It is the first complete quantum computing system built entirely in India. 
  • It includes both hardware and software, covering everything from the quantum processor to AI-driven application tools to efficiently run quantum applications. 
• Performance: The system boasts 25 qubits, crucial for high-performance quantum computing; 
  • It enables faster complex calculations with enhanced stability and minimal error rates compared to traditional computers. 
• Applications: It has potential uses in life sciences (drug discovery, genomics), materials science (designing new materials), mobility and logistics (route and supply chain optimization).  

World Quantum Day  

• It was launched in 2021, to commemorate Planck's constant (4.14), a fundamental quantity in quantum physics, and to promote awareness of quantum science and its technological impact.  
• The date was chosen because 14th  April (“4.14”) represents the first three digits of Planck's constant (4.14 × 10⁻¹⁵ eVs) when rounded up. 
• The UN has designated the year 2025 as the ‘International Year of Quantum Science and Technology’.
