At the Quantum India Summit 2025, experts showcased how the fusion of quantum physics and artificial intelligence is no longer just a theoretical pursuit. It is now driving real-world innovations—from simulating cancer at the cellular level to creating radiation-free cardiac diagnostics—ushering in a new era of predictive, personalised, and safer healthcare.
Quantum Tech Targets Cancer and Clinical Trials
As reported by TOI, Anupama Roy from IBM Bengaluru explained how quantum computing is transforming disease research, particularly in oncology. By using quantum conditional optimal transport, researchers can now model drug behaviour at the cellular level, predicting how a drug moves through and affects cells.
“Many cancer patients don’t die from the disease itself but from treatment-related complications,” Roy noted. “Understanding intracellular drug pathways using quantum tools may help reduce those risks.”
Roy also discussed how quantum analytics, combined with machine learning, is improving clinical trials. These tools can monitor patient behaviour, track drug adherence, and optimise trial outcomes in real time.
Quantum Sensors Revolutionise Cardiac Diagnosis
Shifting focus from computing to sensing, Pranab Dutta, founder of GDQ Labs Pvt Ltd, described how quantum sensors can detect the ultra-weak magnetic fields generated by the human heart. Unlike ECGs, which are affected by variables like skin and fat thickness, optically pumped magnetometers offer a uniform, 3D mapping of cardiac activity without radiation or contrast agents.
“This technology has the potential to replace not just ECGs, but also stress tests and even MRIs,” said Dutta, emphasising its diagnostic versatility and safety.
Quantum Light Enables Safer, Real-Time Imaging
Associate Professor Varun Raghunathan from IISc presented advances in quantum-enhanced imaging. Traditional methods like fluorescence microscopy and MRI rely on dyes and contrast agents to highlight tissues. However, quantum light can offer real-time, dye-free visibility inside the body.
“Quantum imaging allows surgeons to see inside the body during operations and make fast, accurate decisions—without the risk of radiation or toxic dyes,” Raghunathan explained.
Box: How Quantum Tech Is Transforming Healthcare
