Quanfluence Raises $10M to Build India's Photonic Quantum Computer

Quanfluence, a Bengaluru deep tech startup, has raised $10 million to build a full-stack photonic quantum computer. Chiratae Ventures led the round, with participation from Pi Ventures and Rainmatter by Zerodha, The Quantum Insider reported.

The company is targeting early processors by 2027 and larger, scalable systems by 2029, a timeline that would place an Indian-designed machine in a field led by far better funded companies in the United States, Canada and Europe.

What Quanfluence Is Building

Quanfluence builds quantum computers that use particles of light, or photons, to carry and process information. Most of the best-known quantum machines rely on superconducting circuits cooled to temperatures near absolute zero. Photonic systems take a different route, and their supporters argue they can be manufactured using techniques borrowed from the semiconductor and telecom industries and linked together over optical fiber.

The company describes its approach as full-stack. That means it is developing the photonic chips, the control electronics and the software as one integrated system instead of sourcing them separately. Its work spans photonic integrated circuits, electronic integrated circuits, quantum light generation, photonic devices and the coupling between chips and fiber.

Quanfluence says the photonic chips at the center of the planned machine are designed in India.

The Team Behind Quanfluence

Founded in 2021 and incubated at the IIT Madras Incubation Cell, Quanfluence is led by co-founder and CEO Sujoy Chakravarty. The founding team also includes Ravi Mehta, Biman Chattopadhyay and Aditi Vaidya, along with two academics, Prof. Anil Prabhakar of IIT Madras and Prof. Sandeep Goyal of IISER Mohali.

"Our goal at Quanfluence has never been to build a better experiment. It has been to build a useful quantum computer," Chakravarty said.

Products Already on the Market

Unlike many quantum startups at this stage, Quanfluence already sells hardware. It has productized a photonic Ising machine, a specialized system built to solve optimization problems, and offers several quantum devices commercially.

That gives the company customer feedback while it works on the larger goal, and it shows investors that the team can move technology out of the lab and into a product.

How Quanfluence Will Use the $10M

The funding will go toward building the full-stack photonic quantum computer, integrating the company's own photonic chips with its control electronics and software layers.

By global standards the round is modest. Leading photonic quantum companies elsewhere have raised hundreds of millions of dollars or more. Quanfluence is betting that tight integration and in-house chip design will let it make progress on a smaller budget.

Why the Quanfluence Funding Matters

India has made quantum technology a national priority, and the government has committed public funding to build domestic capability. Private capital has been slower to follow, in part because quantum hardware takes years to mature and returns are uncertain.

A $10 million round led by one of the country's established venture firms suggests that is beginning to change. For Quanfluence, the next two years will be about hitting its 2027 processor milestone and showing that its architecture can scale toward the larger systems it has promised by 2029.
