November 12, 2025 – In a groundbreaking achievement, IIT Bombay research has led to the development of India’s first indigenous Quantum Diamond Microscope for 3D magnetic imaging.
The innovation was unveiled under the National Quantum Mission (NQM) and marks a historic step in quantum sensing, positioning India as a global leader in advanced technology.
IIT Bombay’s Quantum Diamond Microscope
The Quantum Diamond Microscope (QDM) was designed by the P-Quest Group at IIT Bombay, led by Professor Kasturi Saha. Built on nitrogen-vacancy (NV) centers in diamond, the device enables dynamic magnetic field imaging at the nanoscale.
This breakthrough allows researchers to visualize magnetic fields in three dimensions with unmatched precision. Notably, the QDM has earned India its first patent in quantum sensing, underscoring the country’s progress in advanced science and technology.
Applications of 3D Magnetic Imaging
The QDM is expected to revolutionize multiple fields, including neuroscience, semiconductor research, and materials science.
For example, scientists can now map magnetic fields inside encapsulated chips without damaging them, a process crucial for next-generation electronics.
Additionally, the technology can help study brain activity by tracking magnetic signals at the cellular level. Reports suggest that more than 40 research institutions across India are preparing to collaborate with IIT Bombay to explore practical applications of the device.
National Quantum Mission and Global Impact
The announcement was made during the Emerging Science, Technology and Innovation Conclave (ESTIC 2025), attended by Union Minister Dr. Jitendra Singh and senior officials from the Department of Science and Technology.

According to Swarajya News, the QDM positions India as a global player in quantum sensing, a field projected to reach a market size of $3.5 billion by 2030. Meanwhile, experts believe this indigenous development will reduce dependence on foreign technology and accelerate India’s scientific self-reliance.
With this milestone, IIT Bombay has not only advanced India’s quantum research but also set the stage for international collaborations.
The Quantum Diamond Microscope is expected to become a cornerstone of the National Quantum Mission, driving innovation across industries and strengthening India’s role in the global technology race.
