Bengaluru-based deep technology company Quanfluence secured USD 10 million in a funding round led by Chiratae Ventures to build a full-stack photonic quantum computer. The investment will support development of the company’s integrated system, combining custom photonic chips, control electronics and software, with early processors planned for 2027. “Our goal at Quanfluence has never been to build a better experiment. It has been to build a useful quantum computer,” said Sujoy Chakravarty, Co-founder and CEO, emphasizing the company’s focus on scalable quantum computing through photonics.
Chiratae Ventures Leads $10 Million Funding for Quanfluence
Chiratae Ventures spearheaded a $10 million funding round for Quanfluence, a deep technology company focused on constructing a complete photonic quantum computer system. The investment includes renewed support from Pi Ventures, which previously led Quanfluence’s seed funding in 2024, and initial participation from Rainmatter by Zerodha. This capital injection will directly fuel the development of an integrated system encompassing custom photonic chips, control electronics and a dedicated software layer.
Quanfluence anticipates delivering early-stage processors by 2027, with plans for larger, scalable machines to follow by 2029. Since securing its initial funding, Quanfluence has demonstrably advanced core technologies essential to its full-stack architecture. The company has successfully designed and fabricated multiple photonic integrated circuits (PICs) and electronic integrated circuits (EICs), addressing a key challenge in quantum computing hardware. They have developed low-loss chip-to-fiber coupling designs and achieved the generation of quantum light states, critical components for manipulating and reading quantum information.
Parallel to these hardware advancements, Quanfluence has transitioned some of its technology beyond the research laboratory, productizing a photonic Ising machine and making several quantum devices commercially available, the company says. The team’s background is uniquely positioned for this undertaking, having previously established Silicon and Beyond, a semiconductor IP company later acquired by Synopsys. This prior experience in chip design, combined with expertise in quantum optics, allows Quanfluence to maintain a fully in-house development process, according to the company.
Venkatesh Peddi, Managing Director & Partner at Chiratae Ventures, highlighted the firm’s commitment to backing indigenous deeptech ventures led by exceptional founders. Pi Ventures’ follow-on investment reflects growing confidence in Quanfluence’s progress.
The company was founded in 2021 by Sujoy Chakravarty, Ravi Mehta, Biman Chattopadhyay, Aditi Vaidya, Prof. Anil Prabhakar of Madras and Prof. Sandeep Goyal of IISER Mohali, and is currently incubated at Madras Incubation Cell. Rainmatter by Zerodha also recognizes the shift occurring in the quantum computing landscape, moving from academic exploration to industrial-scale development. This funding round positions Quanfluence to accelerate its development of a full-stack photonic quantum computer, potentially reshaping quantum computing hardware.
Our goal at Quanfluence has never been to build a better experiment. It has been to build a useful quantum computer. We chose photonics because we believe it gives us a path to scale. Over the last few years, we have built the core pieces: the ICs, the electronics, the optics and the algorithms. This funding allows us to bring those pieces together into a complete system.
