Quantum Source is an Israeli startup developing, technology for powerful, cost-effective and practical photonic quantum computers. The firm raised $50 million in a Series A investment round led by Eclipse, bringing its total funding to date to $77 million.
Photonic quantum computers are a promising avenue of research that leverages the principles of quantum mechanics to perform calculations beyond the capabilities of classical computers. Unlike classical computers, which use bits (0 or 1) to represent information, photonic quantum computers utilize photons (particles of light) as quantum bits, or qubits.
Photonic quantum computers use optical components, such as lasers, waveguides, and interferometers, to manipulate and measure photons. By exploiting quantum phenomena like superposition and entanglement, these computers can perform complex calculations in parallel and solve problems that are intractable for classical computers.

Quantum Source was founded in 2021 by semiconductor industry veterans and serial entrepreneurs Oded Melamed, Gil Semo, and Dan Charash, and Professor Barak Dayan, a world-leading scientist in the field of quantum optics, who saw an opportunity to solve one of the biggest challenges of photonic quantum computing. The team has taken a novel approach that harnesses single atoms trapped on a proprietary photonic chip to allow deterministic photon generation and entanglement. This results in four orders of magnitude better efficiency compared to other implementations, making the Quantum Source system substantially more scalable, compact, and simpler to control.
“This round is a vote of confidence in our approach to making scalable, useful quantum computing a reality, and a testament to the broader opportunity in quantum computing,” said Oded Melamed, Co-Founder and CEO of Quantum Source. “Our game-changing approach, which combines photonic and atomic qubits, will propel quantum computing further toward commercialization, by making large-scale, fault-tolerant quantum computers available to corporations at a practical cost.”
Quantum Source, a company with 45 employees, over half of whom possess PhDs, is well-positioned to drive growth and innovation in the photonic computing industry. Last year, the company secured a $12 million seed extension led by Dell Technologies Capital and added former Israeli Prime Minister Naftali Bennett to its Board of Directors. Bennett’s extensive experience in technology leadership will be invaluable in guiding Quantum Source’s mission.
