Quantum Diamond Microscopy: IIT Bombay Innovation Boosts Neuroscience And Semiconductor Research
In a significant milestone for India’s quantum technology ecosystem, the P-Quest Group at IIT Bombay has unveiled the nation’s first Quantum Diamond Microscope (QDM). This innovation is part of the National Quantum Mission (NQM), spearheaded by the Department of Science and Technology (DST). The development of the QDM represents a major leap in quantum sensing, earning India its first patent in the field of Quantum Diamond Microscopy.
Revolutionizing Magnetic Field Imaging
Formally introduced at the Emerging Science Technology and Innovation Conclave (ESTIC 2025), the Quantum Diamond Microscope is designed for dynamic magnetic field imaging. This technology has wide-ranging implications across various fields, including neuroscience, materials research, and semiconductor diagnostics.
The QDM enables non-destructive evaluation of encapsulated semiconductor chips by mapping magnetic fields in three-dimensional (3D) layers. This provides unparalleled insight into chip behavior and functionality, which is crucial for advancing semiconductor technology.
Official Unveiling and Key Figures
The official unveiling of the Quantum Diamond Microscope took place in the presence of several dignitaries, including:
- Dr. Jitendra Singh, Union Minister for Science and Technology
- Prof. Ajay K Sood, Principal Scientific Adviser to the Government of India
- Prof. Abhay Karandikar, Secretary, DST
Development by IIT Bombay’s P-Quest Group
The breakthrough was achieved by the P-Quest Group, led by Professor Kasturi Saha. The team utilized nitrogen-vacancy (NV) centers in diamond, which are atomic-scale defects characterized by strong quantum coherence even at room temperature. These NV centers act as sensitive probes for detecting magnetic, electric, and thermal variations at the nanoscale.
Through a technique known as optically detected magnetic resonance (ODMR), the Quantum Diamond Microscope translates fluorescence data into precise magnetic field images. This allows for widefield, nanoscale 3D visualization comparable to traditional optical microscopy.
Implications for Semiconductor and Biological Research
As technology advances, the complexity of 3D chip architectures, cryogenic processors, and autonomous electronics increases. Traditional diagnostic instruments often face limitations in mapping internal charge and current paths. The Quantum Diamond Microscope addresses these constraints, enabling researchers to directly observe buried current networks and multilayer charge flow in real time.
Aligned with the National Quantum Mission, Professor Saha’s team at IIT Bombay envisions the integration of Quantum Diamond Microscopy with artificial intelligence (AI) and machine learning-based computational imaging. This integration aims to unlock new possibilities in chip diagnostics, biological imaging, and geological magnetization studies.
Strengthening India’s Position in Quantum Technology
This pioneering development not only strengthens India’s position in global quantum technology research but also opens avenues for multidisciplinary innovation across scientific and industrial domains. The Quantum Diamond Microscope is expected to play a crucial role in advancing both neuroscience and semiconductor research, paving the way for future innovations.
Conclusion
The introduction of the Quantum Diamond Microscope by IIT Bombay marks a significant advancement in the field of quantum sensing. With its potential applications in various scientific and industrial sectors, this innovation is set to enhance our understanding of complex systems and drive future research.
