Quamcore

QuamCore Ltd. is an Israeli deep-tech company developing an architecture for superconducting quantum computers intended to scale to one million qubits inside a single cryostat. The company emerged from stealth in March 2025 after roughly two years of development, presenting a fully designed and simulated processor architecture rather than operating hardware. Its stated premise is that about one million qubits is the minimum system size needed for practical quantum advantage in fields such as drug discovery, materials science, AI and energy, and that the binding constraint on today's superconducting systems is scaling rather than qubit fidelity or coherence.

The core technical approach is to embed ultra-low-power superconducting digital control logic directly inside the cryogenic chamber, next to the qubits, instead of placing control electronics outside it. According to the company this cuts the number of cables required by a factor of more than 1,000, removing the thermal bottleneck and space constraints that currently cap superconducting systems at roughly 5,000 qubits per cryostat in systems from IBM and Google. The architecture, protected by multiple patents, also incorporates built-in error correction as a step toward fault-tolerant operation. At seed stage the company said the design would allow a million-qubit machine to fit in a roughly 50 cm cube, with sharply reduced power consumption and cost compared with multi-cryostat approaches, and would permit machines to be networked to increase qubit capacity.

The founding team is CEO Alon Cohen, CTO Prof. Shay (Shai) Hacohen-Gourgy of the Technion – Israel Institute of Technology, and chief scientist Prof. Serge Rosenblum of the Weizmann Institute of Science. Cohen is an alumnus of IDF Unit 8200 with about 25 years in intelligence systems and communication chip development, co-founded the EyeC Radar group at Mobileye (Intel) where he was chief architect and head of the radar algorithm group, holds more than 40 patents in radar, communications and signal processing, and received Intel's internal innovation award. Hacohen-Gourgy and Rosenblum each have over 15 years of experimental quantum research experience, did postdoctoral work at UC Berkeley and Yale, and built superconducting quantum laboratories at the Technion and the Weizmann Institute. Prof. Eby G. Friedman of the University of Rochester, a specialist in superconducting digital circuits, serves as senior advisor.

Founding story

QuamCore was founded in 2022 by Alon Cohen, a technology leader from Mobileye, together with two Israeli academics, Prof. Shay Hacohen-Gourgy of the Technion and Prof. Serge Rosenblum of the Weizmann Institute of Science. The founders set out to address the scaling problem that keeps quantum computers from practical use, concluding that one million qubits was the threshold for real-world value and that reaching it required rethinking quantum processor architecture, including a shift to digital control, new superconducting devices and a ground-up processor redesign. Cohen has said the underlying control technology traces to work he did at Intel's Mobileye subsidiary, where it was applied to autonomous-vehicle perception.

Traction

As of the March 2025 seed announcement the architecture existed as a detailed design and simulation only, with first chips expected to enter production at a major semiconductor fabrication plant and testing to follow. The August 2025 Series A was raised to move from design to fabrication of first-generation processors, establish a dedicated quantum lab and scale operations. Total disclosed funding stood at $35 million, including $4 million in non-dilutive Israel Innovation Authority grant funding plus about $1 million from the authority at seed stage.

Latest developments

On 4 August 2025 QuamCore announced a $26 million Series A led by Sentinel Global with participation from Arkin Capital and returning investors Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium and qbeat/Quantum Leap, plus a $4 million non-dilutive Israel Innovation Authority grant, bringing total funding to $35 million. The company said it would use the capital to fabricate its first-generation processors, accelerate chip production and prototype integration, build a dedicated quantum lab and grow its team.
