Quanfluence Raises $10 Mn To Build Full-Stack Photonic Quantum Computer

Bengaluru-based quantum computing startup Quanfluence has secured $10 million in funding to develop its full-stack photonic quantum computing system. Led by Chiratae Ventures, Rainmatter by Zerodha, and existing backer Pi Ventures, the investment will support the creation of indigenously designed photonic chips, control electronics, and software integrated into a unified architecture.

The company aims to deliver early processors by 2027, followed by larger, scalable machines by 2029. Founded in 2021 by a team of five individuals, Quanfluence is constructing a universal photonic quantum computer, having previously developed a quantum-inspired optical Ising machine. Utilizing light waves as computational units, the startup's technology can process hundreds of interconnected variables simultaneously, achieving speeds 100 times faster than traditional optimization methods.

Quanfluence has already commercialized its optical Ising machine, selling physical systems to customers and offering remote access on a usage basis. The startup has already sold three machines and is conducting paid pilots with 10-15 corporations. While the company has already proved the concept, its primary challenge lies in integrating components, scaling manufacturing, and navigating chip production and hardware delivery cycles.

Currently employing 25 people, Quanfluence aims to expand its workforce to 40 employees within the next year. The company has already raised $2 million in a seed round in December 2024 to accelerate development and scale near-term products. As investors increasingly explore deeptech bets with commercial applications, quantum computing, still largely experimental, is gaining traction.

Quanfluence's photonics-led approach, targeting scalability from prototypes to systems with millions of qubits, aligns with India's National Quantum Mission, which is fostering collaboration between startups, researchers, and government-backed quantum hubs.
