Israeli deep-tech startup QuamCore has secured $26 million in a Series A funding round to develop a groundbreaking quantum computer capable of supporting 1 million qubits in a single cryostat, the company announced Monday.
The investment, which brings QuamCore’s total funding to $35 million, was led by Sentinel Global with participation from Arkin Capital, Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, Qbeat Ventures and a $4 million non-dilutive grant from the Israel Innovation Authority.
The funding will support QuamCore’s mission to overcome quantum computing’s scalability barriers, enabling real-world applications in fields like drug discovery, advanced materials, artificial intelligence and energy.
Unlike current superconducting quantum systems, such as those developed by Google and IBM, which manage around 5,000 qubits per cryostat, QuamCore’s innovative architecture is designed to scale to 1 million qubits in a single unit. The breakthrough eliminates the need for costly and complex multi-cryostat setups, significantly reducing size, cost and energy demands.
QuamCore’s approach integrates superconducting digital control logic directly into the cryostat, slashing cabling requirements and resolving thermal bottlenecks that have hindered large-scale quantum systems. The design also incorporates built-in error correction, a key step toward fault-tolerant quantum computing.

“Scaling to 1 million qubits is the threshold for real-world quantum advantage,” said QuamCore CEO Alon Cohen. “Our architecture rethinks superconducting qubits, the most mature and high-performing platform, to create a compact, scalable system. This funding accelerates our path to chip production and prototype integration.”
The startup’s founding team combines expertise in quantum information, superconducting devices and large-scale semiconductor systems. With the new capital, QuamCore plans to begin fabricating its first-generation quantum processors, establish a dedicated quantum lab, and expand operations.
“QuamCore’s roadmap to a million-qubit machine is a game-changer for superconducting quantum technology,” said Dror Sharon, Partner at Sentinel Global. “Their innovation redefines how we approach scaling, making quantum computing more practical and impactful.”
Arkin Capital CEO Nir Arkin added that “by embedding control logic inside the cryostat, QuamCore removes a critical barrier to scaling. This approach could unlock markets worth trillions by making million-qubit systems economically viable.”
QuamCore’s technology aims to maintain superconducting qubits’ lead in the quantum computing race. The company’s patented architecture is designed to deliver fault-tolerant, scalable systems, positioning QuamCore to drive transformative advancements across industries.
