QuamCore, an Israeli quantum computing startup, has raised $26 million in a Series A round led by Sentinel Global, with participation from Arkin Capital, Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, and Quantum Leap.
The Israel Innovation Authority also contributed a $4M non-dilutive grant, bringing total funding to $35M.
The goal: one million qubits in a single cryostat
QuamCore is developing what could be the world’s first million-qubit quantum computer using a radically simplified hardware architecture. Unlike current systems that require dozens of interconnected cryostats to scale, QuamCore’s design supports 1 million superconducting qubits in just one cryostat, slashing thermal complexity and dramatically lowering cost.
This innovation tackles the biggest bottleneck in quantum hardware today — control wiring and cryogenic scaling — which has limited most existing systems to ~5,000 qubits.

From simulation to silicon
With the new funding, QuamCore will transition from architectural simulation to physical fabrication, launch a dedicated quantum lab, and expand its team. The goal: prove out its design in real hardware and create a platform that can power fault-tolerant, real-world quantum applications.
“Our architecture was designed from day one to hit the number that matters — a million qubits,” said CEO Alon Cohen, a former Mobileye and IDF Unit 8200 exec. “The superconducting platform is ready. Now we’re building the machine.”
Founders combine scientific pedigree and commercial chops
QuamCore’s founding team includes:
- Alon Cohen, tech veteran with 25+ years in sensing and radar, co-founder at EyeC Radar (Mobileye)
- Prof. Shai Hacohen-Gourgy, quantum computing expert at Technion Institute, with 15+ years in superconducting systems
- Prof. Serge Rosenblum, physicist at the Weizmann Institute, known for his work on quantum optics and fault-tolerant logic
Embedded control logic: the architectural breakthrough
At the core of QuamCore’s innovation is its superconducting digital control logic embedded inside the cryostat. This eliminates thousands of external cables — the biggest thermal bottleneck in today’s machines — and enables a compact, energy-efficient design. Built-in error correction is also natively integrated, tackling noise and system instability at the hardware level.
Industry implications: from chemistry to AI
By delivering a scalable quantum architecture, QuamCore aims to unlock trillion-dollar markets across:
- Drug discovery (faster simulation of molecules)
- Materials science (novel battery chemistry)
- AI & optimization (quantum-enhanced algorithms)
“QuamCore isn’t just iterating — they’ve reset the blueprint for scalable quantum machines,” said Dror Sharon, Partner at Sentinel Global.
