India has developed its first indigenous Quantum Diamond Microscope (QDM) for dynamic magnetic field imaging, marking a major milestone in the field of quantum sensing. The breakthrough, achieved by the P-Quest Group at IIT Bombay under the National Quantum Mission (NQM) of the Department of Science and Technology (DST), was announced during the Emerging Science Technology and Innovation Conclave (ESTIC 2025).

Union Minister for Science and Technology Dr. Jitendra Singh, Principal Scientific Adviser Prof. Ajay K. Sood, and DST Secretary Prof. Abhay Karandikar were present at the announcement ceremony.

The QDM, led by Professor Kasturi Saha’s team, is based on nitrogen-vacancy (NV) centers in diamond — atomic-scale defects that retain quantum coherence at room temperature. These NV center
