QuamCore raises $26M in Series A funding

• QuamCore, an emerging quantum computing company, has secured $26 million in Series A funding.
• QuamCore claims to have developed a fully designed and simulated architecture capable of scaling to 1 million qubits.
• Arkin Capital was joined by existing investors Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, and Quantum Leap

QuamCore, an emerging quantum computing company, has secured $26 million in Series A funding, 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. Also, the Israel Innovation Authority contributed a $4 million non-dilutive grant.

A key focus of QuamCore is scaling the ability of quantum systems to handle millions of qubits for applications like drug discovery, advanced materials, AI, and energy.

While current advanced superconducting quantum systems, including those from Google and IBM, can support over 5,000 qubits per cryostat, QuamCore claims to have developed a fully designed and simulated architecture capable of scaling to 1 million qubits – in a single cryostat. According to the company, this capability changes the economics of quantum computing by eliminating the need for massive multi-cryostat infrastructure.

At the heart of QuamCore’s approach is the way it tightly integrates superconducting digital control logic directly into the cryostat, which it says reduces the cabling burden by orders of magnitude and eliminates the primary thermal bottleneck that has blocked large-scale adoption. The design also includes built-in error correction, a critical feature for achieving fault-tolerant quantum computing.

QuamCore’s founding team blends deep expertise in quantum information, superconducting devices, and large-scale semiconductor systems. The company will use the new funding to move from design to fabrication of its first-generation processors, establish a dedicated quantum lab, and scale up operations.

“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 Cohen, CEO of QuamCore. “We chose to radically rethink the architecture of the most mature and performant platform: superconducting qubits. The result is a blueprint that can scale, stay compact, and remain aligned with where the industry is already headed.”
