Photonic quantum technology 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. The Bengaluru-based startup had earlier raised $2 million in a seed round led by Pi Ventures, with participation from Golden Sparrow, Reena Dayal and others in December 2024. The fresh funds will be used to build and launch a four-qubit quantum computer in the near term, with the company targeting a larger prototype featuring around 100 qubits by 2029, Quanfluence said in a press release. Founded in 2021 by Sujoy Chakravarty, Ravi Mehta, Biman Chattopadhyay, Anil Prabhakar, Aditi Vaidya and Sandeep Goyal, Quanfluence develops photonic quantum computing technology for optimisation problems. Its hardware-based solution is designed to complement AI in decision-making. The company aims to develop a fault-tolerant, general-purpose quantum computer over the next five to six years. Unlike conventional quantum computing systems that require complex cooling infrastructure, Quanfluence’s technology combines optics and hardware to operate at room temperature. Its optical Ising machine uses light waves and FPGAs for optimisation processing, which the company claims can be up to 100 times faster than classical computing for certain workloads. The startup’s system is designed to address high-dimensional optimisation problems across areas such as logistics, workforce scheduling, risk management and financial optimisation. Quanfluence is also testing an advanced version of its system capable of processing 10-25 million permutations for complex optimisation problems, including financial risk management, logistics and delivery route planning. The sector has been gaining traction amid the government’s Rs 6,003.65-crore National Quantum Mission, which includes photonic technologies among the platforms being developed for quantum computing. Other startups in the space have also attracted investor interest. QpiAI raised $32 million in Series A funding last year from Avataar Ventures and the National Quantum Mission, while BQP, formerly known as BosonQ Psi, raised about $5 million in seed funding this year for its quantum-inspired simulation technology. QuBeats, another deeptech startup working on quantum sensing and advanced laser technologies, raised $15 million in its first institutional round in April from Zoho Corporation, Indusbridge Ventures and the National Quantum Mission, along with government grant support.
