IIT Bombay Unveils First Make-in-India Quantum Diamond Microscope For Advanced Magnetic Imaging
Mumbai, Nov 12, 2025 – Researchers at the Indian Institute of Technology (IIT) Bombay have made a significant breakthrough in the field of quantum technology by developing the country’s first indigenously built Quantum Diamond Microscope (QDM). This innovative instrument is designed for dynamic magnetic field imaging, marking a pivotal advancement in India’s quantum technology ecosystem.
Significance of the Development
The unveiling of the Quantum Diamond Microscope was announced during the Emerging Science, Technology and Innovation Conclave (ESTIC 2025), attended by prominent figures in the science and technology sectors, including Union Minister Dr. Jitendra Singh. This achievement is a notable milestone under the National Quantum Mission (NQM) initiated by the Department of Science and Technology (DST) and represents India’s first patent in this specific domain.
Technology Behind the Quantum Diamond Microscope
The QDM is based on the unique properties of nitrogen-vacancy (NV) centers in diamonds. These atomic-scale defects occur when a nitrogen atom is adjacent to a missing carbon atom within the diamond lattice. The NV centers are remarkable because they maintain quantum coherence even at room temperature, which allows for the extremely sensitive detection of magnetic, electric, and thermal fields.
How It Works
The microscope utilizes spin-dependent fluorescence and optically detected magnetic resonance (ODMR) techniques to optically read local magnetic fields with high spatial precision. This capability enables widefield, three-dimensional magnetic imaging at the nanoscale, providing a non-destructive method for visualizing internal magnetic activity in various materials and devices.
Applications of the Quantum Diamond Microscope
The potential applications of the QDM are vast and varied, including:
- Neuroscience: The ability to visualize and understand magnetic fields in biological systems.
- Materials Research: Investigating the magnetic properties of new materials and composites.
- Semiconductor Diagnostics: Imaging multilayered circuits and encapsulated chips in advanced electronics.
- 3D Chip Architecture Mapping: Mapping magnetic fields in complex chip designs, including batteries and cryogenic processors.
Challenges and Future Directions
While the QDM presents exciting opportunities, it also faces challenges, particularly in areas where conventional diagnostic tools fall short. The IIT Bombay team is committed to overcoming these hurdles by integrating QDM technology with artificial intelligence (AI) and machine learning-based computational imaging. This integration is anticipated to broaden the scope of applications to include:
- Biological imaging, enhancing the understanding of complex biological systems.
- Geological magnetization studies, providing insights into earth sciences.
- High-precision quantum sensing applications, pushing the boundaries of current sensing technologies.
Strengthening India’s Position in Quantum Technologies
The development of the Quantum Diamond Microscope aligns with the objectives of the National Quantum Mission, which aims to position India as a leader in emerging quantum technologies. By fostering innovation and encouraging research in this field, India is taking significant steps toward enhancing its global standing in quantum science and technology.
Conclusion
The unveiling of the Quantum Diamond Microscope by IIT Bombay is a landmark achievement that not only showcases India’s capabilities in advanced technology but also opens up new avenues for research and application across various scientific fields. As the nation continues to invest in quantum technologies, the QDM stands as a testament to the potential of indigenous innovation in driving scientific progress.
