QuamCore Secures $26M Series A to Build 1-Million-Qubit Quantum Computer in a Single Cryostat

TEL AVIV, Israel, Aug. 04, 2025 (GLOBE NEWSWIRE) -- QuamCore, a deep-tech startup tackling quantum computing's hardest scalability challenges, announced a $26 million Series A, bringing total funding to $35 million. The round was led by Sentinel Global, with participation from Arkin Capital, as well as existing investors Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, and Quantum Leap. The Israel Innovation Authority contributed a $4 million non-dilutive grant.

To make quantum computing viable for real-world impact in areas like drug discovery, advanced materials, AI, and energy, systems will need to manage millions of qubits, far beyond the limits of current hardware. While today's most advanced superconducting quantum systems, like those from Google and IBM, can support ~5,000 qubits per cryostat, QuamCore has developed a fully designed and simulated architecture capable of scaling to 1 million qubits, in a single cryostat. This milestone, long considered out of reach, fundamentally changes the economics of quantum computing by eliminating the need for massive multi-cryostat infrastructure.

"From day one, we focused on the minimum viable system to unlock real-world quantum advantage, and that number is 1 million qubits," said Alon ...
