Quantum Source
Overview
Scalable photon sources for photonic quantum computing. Proprietary technology based on Weizmann Institute research for deterministic, high-quality entangled photon generation — a critical missing component for photonic quantum computers.
Key Milestones
- 2021: Founded by CEO Gil Semo and Prof Benny Dayan (Weizmann Institute)
- 2024: $50M Series A raised (Dell Technologies Capital, Eclipse Ventures)
- 2025: Developing scalable photon source technology for photonic quantum computing
Technology Approach
Quantum Source addresses a fundamental bottleneck in photonic quantum computing: generating entangled photons reliably and at scale. Founded by Prof Benny Dayan (Weizmann Institute of Science), the company develops deterministic photon sources that could replace the probabilistic sources used by current photonic quantum computers.
Probabilistic photon sources are a key limitation — they succeed only a fraction of the time, requiring exponential overhead as systems scale. Quantum Source’s approach aims to make photon generation deterministic, which would dramatically improve the efficiency and scalability of photonic quantum architectures used by companies like PsiQuantum and Xanadu.
Competitive Position
Strengths: Addresses a universal need across photonic quantum computing. Strong academic foundation (Weizmann Institute). Well-funded with strategic investors (Dell, Eclipse).
Challenges: Component supplier dependent on photonic QC ecosystem success. Technology must prove scalability advantages over existing probabilistic approaches. Competing with Quandela’s quantum dot sources.
