Israel-based Startup Quantum Source Out of Stealth With $15M Seed Round

Quantum Source, an Israel-based quantum computing startup, has come out of stealth mode with a $15 million Seed funding round co-led by Grove Ventures, Pitango First and Eclipse Ventures.

The company, set up by Oded Melamed, Gil Semo, Dan Charash, and Professor Barak Dayan — a Senior Scientist and founder and head of the Quantum Optics lab at the Weizmann Institute of Science —  intends to enable the scaling quantum computers to millions of qubits with its proprietary photonic technology. Currently, the company employs twenty-five physicists and engineers, fifteen of whom hold Ph.D. degrees.

“The difference between small quantum computers that are developed today, with tens or hundreds of qubits, and building efficient, large-scale quantum computers with millions of qubits is huge,” said Oded Melamed, Quantum Source’s CEO and one of four Co-Founder. “The photonic quantum technology that Quantum Source is developing will enable a dramatic leap forward and the realization of quantum computer systems with millions of qubits. These new full-scale quantum computers will have a significant impact on many industries, solving previously computationally impossible problems in multiple sectors, such as drug and material development, finance, and cybersecurity.”

Like many companies in the quantum computing field, Quantum Source claims its Photonic quantum computing approach is the “only way to deliver useful quantum computers”. There are several companies working on this approach globally. There is ORCA Computing in the UK, Xanadu in Canada and PsiQuantum in the USA to name a few (see our quantum data platform for a full list). Quantum Source will be the first funded Israeli company working on the qubit modality, which is touted to offer an alternative route to useful quantum computers.

Quantum Source claim their approach is differentiated through their method of entangling photons, one of the key challenges to creating useful qubits. We understand they are planning to develop chips that can be manufactured without specialist facilities and do not need to operate with any cooling – a prerequisite for many other qubit modalities.

The business’ vision is to build quantum computers that can scale to millions of qubits, an amount that many in the industry see as a prerequisite for significant applications such as better drug discovery.
