Quanfluence Raises $10 Million to Build India Photonic Quantum Computer, Targets 100 Qubits by 2029

Quantum computing usually conjures images of machines cooled to near absolute zero inside giant labs. A Bengaluru company is betting that light can do the job at room temperature, and Indian investors are backing it.

Quanfluence, a Bengaluru deep technology company building photonic quantum computers, raised $10 million in a round led by Chiratae Ventures. Pi Ventures and Rainmatter by Zerodha also took part. Pi Ventures led the company's earlier $2 million seed round, so the new round is five times the size of that first raise.

What Quanfluence Builds

Founded in 2021 by Sujoy Chakravarty, Ravi Mehta, Biman Chattopadhyay, Anil Prabhakar, Aditi Vaidya and Sandeep Goyal, Quanfluence develops quantum computers that use light instead of cooled circuits. Its approach, designed for optimisation problems in areas such as finance, logistics and healthcare, combines photonic chips, control electronics and software into one full-stack system, and the company says it operates at room temperature. It positions the technology as a complement to AI in decision-making.

Where the Money Goes

The funds will go toward building and launching a four-qubit machine in the near term, with a larger prototype of around 100 qubits targeted by 2029. A 100-qubit target by 2029 is a clear public milestone, and investors will measure progress against it.

Why This Round Matters

Deep technology rounds in India have historically been small, because machines like these take years and heavy capital to build. A $10 million round led by a specialist firm and joined by the earlier seed lead signals that investors see a credible path to hardware milestones, and that follow-on support is available for companies that hit them.

Who Is Backing It

Chiratae Ventures is a long-running Indian venture firm that has backed technology companies across several stages, and its decision to lead a hardware-heavy deep technology round shows growing appetite for the category. Rainmatter by Zerodha adds a well-known Indian fintech founder network, while Pi Ventures, a deep technology specialist, has now backed the company twice.

What This Means for Founders

Founders building deep technology should note how this company framed its raise: a specific, dated product milestone, a full-stack system and an investor group that had already backed the earlier stage. Hardware and science companies raise differently from software ones, since progress shows up in prototypes and not revenue, so plan your seed round and next raise around technical milestones that investors can check. Keep in mind how a larger round affects dilution, because long development timelines often require more than one round before sales begin.
