IIT-Bombay and Tata Consultancy Services (TCS) have collaborated to pioneer India's inaugural Quantum Diamond Microchip Imager, in line with the National Quantum Mission's objective to position India as a prominent global leader in quantum technology.

• The objective is to develop an advanced sensing tool to enhance precision in semiconductor chip examination, reduce chip failures, and improve energy efficiency.
• The Quantum Diamond Microchip Imager, similar to magnetic resonance imaging (MRI), offers non-invasive and non-destructive imaging of semiconductor chips, overcoming the limitations of traditional methods in detecting anomalies as chip sizes decrease.
• It utilises nitrogen-vacancy centres in diamonds and specialised hardware and software, significantly enhancing failure analysis, device development, and optimisation processes. It also visualises three-dimensional charge flow in multi-layer chips for advanced defect identification.
• It will have wide applications in microelectronics, biological and geological imaging, and fine-scale imaging of magnetic fields, among others.
