Bengaluru-based quantum computing startup Quanfluence has reportedly secured $10 million in a funding round led by Chiratae Ventures, with participation from Rainmatter by Zerodha and existing investor Pi Ventures.

The investment will support the company’s efforts to develop photonic quantum computing hardware, expand manufacturing capabilities and advance towards scalable quantum processors.

The funding comes as Quanfluence works to bridge the gap between experimental quantum technologies and commercially deployable computing systems. The IIT Madras-incubated startup is targeting its first quantum processors by 2027, followed by larger, scalable quantum computers by 2029.

The company intends to channel the fresh capital into developing a full-stack photonic quantum computing platform that combines specialised optical chips, control electronics and software within an integrated architecture.

Unlike conventional quantum computing approaches that rely on superconducting circuits or trapped ions, photonic quantum computing uses particles of light, known as photons, to process quantum information.

Commercial Traction Through Optical Computing

Quanfluence is pursuing commercial applications alongside its longer-term quantum computing ambitions.

The startup has developed an optical Ising machine designed to address optimisation problems involving multiple interconnected variables. Such problems arise in areas including resource allocation, scheduling and logistics, where finding efficient solutions becomes increasingly difficult as the number of possible combinations grows.

The machine uses optical processes to perform computations and is designed to handle hundreds of interconnected variables simultaneously.

Importantly, an optical Ising machine is not equivalent to a universal quantum computer. It is a specialised computing system intended for particular classes of optimisation problems, while universal quantum computers are designed to support a broader range of quantum algorithms.

Quanfluence has reportedly sold approximately three optical Ising machines and is conducting paid pilot programmes with 10 to 15 corporate customers. Its commercial model includes direct hardware sales and remote access to computing systems on a usage-based basis.

These activities provide an early route to commercial revenue while the company continues developing its more technically demanding universal quantum computing architecture. However, detailed revenue figures, customer identities and independently assessed performance benchmarks have not been disclosed.

From Photonic Chips to Integrated Quantum Hardware

Founded in 2021 by Sujoy Chakravarty, Ravi Mehta, Biman Chattopadhyay, Aditi Vaidya, Anil Prabhakar and Sandeep Goyal, Quanfluence is building its computing technology around photonic integrated circuits and associated electronics.

The company’s reported technical developments include the design and fabrication of multiple photonic and electronic integrated circuits, improvements in low-loss chip-to-fibre coupling and demonstrations involving the generation of quantum states of light.

These components serve different purposes in regard to photonic quantum hardware. The photonic circuits guide and manipulate light, and electronic components offer auxiliary control capabilities. Chip-to-fibre coupling is an efficient way to transfer optical signals from the integrated devices into external optical systems.

The challenge lies not only in demonstrating individual components but also in integrating them into a reliable system capable of supporting increasingly complex computations.

Quanfluence is also working on manufacturing scale-up, component integration and hardware delivery processes. These capabilities will become increasingly important as it seeks to move from laboratory prototypes towards larger computing systems.

The company currently employs around 25 people and reportedly plans to expand its workforce to approximately 40 over the next year.

Funding Builds on Earlier $2 Million Seed Round

The latest investment follows a $2 million seed funding round in December 2024, which was intended to accelerate quantum computer development and support the expansion of Quanfluence’s near-term products.

The two reported funding rounds amount to $12 million, although the company’s total funding history and the precise structure of its latest investment have not been independently established.

Participation from Chiratae Ventures, Rainmatter and Pi Ventures reflects investor interest in specialised computing technologies that require substantial research and development before reaching commercial maturity.

For Quanfluence, the central question is whether its early optical computing products can support the company’s development journey while it works towards a more versatile quantum computing platform.

The planned milestones in 2027 and 2029 provide a development roadmap, but they remain company targets rather than confirmed product launch dates.

India’s Quantum Computing Ecosystem Expands

Quanfluence’s funding comes amid efforts to develop India’s domestic quantum technology capabilities.

India’s National Quantum Mission provides a policy framework for advancing research, technology development and the wider quantum ecosystem. The initiative covers areas including quantum computing, communication, sensing and materials.

The private investment is also penetrating into various sections of the quantum tech industry. According to reports, in September 2026, quantum cybersecurity firm QNu Labs raised ₹200 crore in a Series A1 funding round led by the National Quantum Mission and Speciale Invest.

While quantum cybersecurity and quantum computing address different technological requirements, both illustrate the range of commercial activity emerging around quantum technologies in India.

For Quanfluence, the immediate opportunity lies in developing and supplying specialised optical computing systems while improving the components needed for future quantum processors.

Its longer-term prospects will depend on whether the company can demonstrate reliable performance, overcome hardware integration challenges and scale its architecture beyond early prototypes.

The $10 million funding gives Quanfluence additional resources to pursue those objectives, but the transition from promising photonic technology to commercially viable, large-scale quantum computers remains a significant technical undertaking.
