Inside India’s Quantum Leap: Labs, Startups and the Next Decade

1. The global context

Quantum computing is moving from research labs to real-world applications, with governments and companies around the world investing heavily in the technology. The United States, China and the European Union have each committed billions to national programmes, and a handful of technology giants are racing to build machines with enough stable qubits to outperform classical computers on useful problems.

For India, quantum computing is not just a scientific pursuit — it is a strategic opportunity to build deep tech capabilities, create high-value jobs, and solve critical problems in sectors like healthcare, energy, agriculture and national security. It is also a chance to avoid repeating the semiconductor story, in which the country became a large consumer of a foundational technology long before it became a producer.

Indian researchers have contributed to quantum theory for decades, but the country has historically lacked the engineering base and sustained funding needed to build machines. That is what the current push is trying to change, by treating quantum technology as an industrial programme as much as a scientific one.

“Quantum technologies will be to the 21st century what semiconductors were to the 20th — a foundational technology with economy-wide impact.” — A sample pull quote for the demo site.

2. India’s quantum journey

India’s National Quantum Mission, announced in 2023, has set the stage for a coordinated push across research, infrastructure, talent and industry collaborations. The mission aims to build intermediate-scale quantum computers, develop secure quantum communication networks, and advance quantum sensing and materials over roughly eight years. Funding is organised around thematic hubs hosted by leading institutes, each focused on one area: computing, communication, sensing and metrology, or materials and devices.

Alongside the hubs, the mission supports shared facilities for fabrication and testing, so that startups and smaller labs do not each need to buy expensive equipment. It also funds fellowships and new graduate programmes intended to grow a pipeline of quantum engineers over the decade.

3. Key players

Research institutions, public laboratories and a growing set of startups are working on hardware, software and the supply chain around it. Superconducting qubits, trapped ions and photonic approaches are all being explored, often in parallel, because no one yet knows which platform will scale best. Several institutes have built small working processors and are now focused on improving qubit quality rather than simply adding more.

Public laboratories bring strengths in precision measurement and communications, and have demonstrated quantum key distribution over fibre between cities. Industrial research centres run by global technology companies in India add another layer, employing researchers who work on algorithms and software for machines located abroad.

4. Startups to watch

Startups are emerging in quantum hardware, software and use cases, often in partnership with academic labs and larger enterprises. Some are building components that every platform needs, such as cryogenic electronics, control systems and single-photon detectors. Others write algorithms and software tools that run on today’s noisy machines or on classical simulators, preparing customers for the hardware that is still to come.

Investors remain cautious, as they are worldwide: quantum hardware is capital-intensive and revenue is years away. But founders report that public grants, mission funding and early contracts from research institutions have made it possible to keep building while the market matures.

5. Opportunities

Real-world applications could transform industries like healthcare, logistics and finance. Chemists hope to simulate molecules accurately enough to speed up drug and materials discovery. Logistics firms are testing quantum-inspired optimisation for routing and scheduling. Banks are exploring risk modelling and portfolio optimisation, while also preparing their systems for the security implications of quantum computers.

Quantum sensing may deliver value even sooner. Ultra-precise magnetometers, clocks and gravity sensors have uses in navigation, mineral exploration, medical imaging and defence, and several of these technologies are closer to deployment than large-scale quantum computers.

6. Challenges

Talent, infrastructure and global collaboration will be critical in the next decade. Quantum engineering demands rare combinations of skills, from cryogenics to error-correction theory, and India competes with well-funded programmes abroad for the same researchers. Specialised equipment, such as dilution refrigerators and precision lasers, is largely imported, and export controls on sensitive technologies add uncertainty.

There is also a risk of fragmentation, with many small groups pursuing similar goals without sharing results or facilities. The hub model is designed to counter that, but making it work requires institutions that are used to competing for funding to collaborate closely instead.

7. The road ahead

The next decade will decide whether India becomes a serious contributor to quantum technology or remains mainly a user of systems built elsewhere. The foundations are in place: a funded national mission, a growing research base and an ecosystem of startups willing to take long bets. What remains is the hardest part, turning laboratory demonstrations into reliable machines and real customers. That will take patience, steady funding and an unusual degree of cooperation between universities, government and industry.
