Chiratae Ventures Leads $10 Million Round in Photonic Quantum Startup Quanfluence
Quantum computing startup Quanfluence has raised $10 million in a funding round led by Chiratae Ventures, with participation from Rainmatter by Zerodha and existing investor Pi Ventures, marking a serious institutional bet on India's homegrown quantum computing ambitions.
Here's what makes Quanfluence's approach genuinely different. Unlike conventional quantum computing systems that require complex, expensive cooling infrastructure to maintain near-absolute-zero temperatures, Quanfluence's technology combines optics and hardware to operate at room temperature. Its optical Ising machine uses light waves and FPGAs (field-programmable gate arrays) for optimisation processing, a method the company claims can run up to 100 times faster than classical computing for certain specialised workloads.
The roadmap ahead is clearly staged. The fresh capital will go toward building and launching a four-qubit quantum computer in the near term, a genuinely modest first step by industry standards, but one with a much bigger ambition behind it, the company is targeting a significantly larger prototype featuring around 100 qubits by 2029.
The investor lineup adds real credibility here. Having Rainmatter, Zerodha's venture arm known for backing fundamentally research-driven and long-horizon bets, alongside Chiratae Ventures and repeat investor Pi Ventures, signals that quantum computing is increasingly being treated as a legitimate, fundable deep-tech category in India, not just an academic curiosity.
The bigger context matters too. Room-temperature quantum computing remains one of the field's hardest unsolved engineering problems globally, and if Quanfluence's optics-based approach genuinely delivers on its speed claims, even at a small four-qubit scale, it could meaningfully lower the cost and complexity barrier that has kept quantum computing largely confined to well-funded national labs and tech giants.
From optics research to a room-temperature quantum machine, Quanfluence's funding round is a reminder that India's deep-tech ambitions are no longer limited to AI and semiconductors alone.
