India's indigenous quantum software stack, built where the research lives.

The thesis.

The next decade of computing will be defined by who can build the software that makes quantum useful. Hardware is one half of the story. The software backbone, the compilers, simulators, runtime, and applications, is the other half. RSL Quantum exists to make sure that backbone is built in India, by Indian researchers, for Bharat and for the world.

How we work.

We do not see quantum as a single product. We see it as a layer that joins compute, intelligence, sensing, materials, and applications. Each pillar is grounded in research from the INTRINSIC Lab at the Centre for SeNSE, IIT Delhi, then translated into software that ships.

Every line of code traces back to a research result. Every benchmark is reproducible. Every claim is supported by evidence. We do not ship vapour.

Where it lands.

The stack lands in defence, space, industry, and academia. DRDO and partner laboratories for mission grade simulation. ISRO and the new space industry for trajectory, sensor, and materials modelling. Industry pilots in pharma, energy, finance, and manufacturing. Joint research programmes with IITs, IISc, and global universities.

The institutional foundation.

RSL Quantum is incubated at FITT, IIT Delhi, approved by the 118th TSSC of FITT in 2026. The intellectual property foundation is six patents filed at IIT Delhi from the INTRINSIC Lab. The company is aligned with the National Quantum Mission.
