Indian Quantum Update
Recent patent filings and faculty research activity indicate continued growth in India's quantum technology sector.
The Indian quantum technology landscape has seen recent activity in patent filings, with companies such as Tata Consultancy Services filing for patents like “Quantum-classical hybrid systems for combinatorial optimisation”. Other notable patents include “Method and System for Quantum Key Distribution Over a Free-Space Optical Link” and “Spintronic device for room-temperature qubit operation”.
The faculty landscape is led by researchers like G. S. Agarwal from the Raman Research Institute and Pasquale Calabrese from The Abdus Salam International Centre for Theoretical Physics.
On the company front, RSL Quantum, a software company based in New Delhi, is a recent entrant in the sector.
