QuamCore Emerges from Stealth with $9 Million in Seed Funding to Build World's First Scalable 1 million Qubit Quantum Computer

Breakthrough in superconducting digital logic removes quantum scaling barriers, paving the way for large-scale quantum computing

HERZLIYA, Israel, March 12, 2025 /PRNewswire/ -- QuamCore, a deep tech startup redefining quantum computing scalability, announced today its emergence from stealth with $9 million in seed funding. Founded in 2022, QuamCore has spent the past two years developing its breakthrough superconducting quantum processor architecture, working in stealth mode to solve the critical scalability challenges that have long prevented practical quantum computing. The company has now emerged with a patented architecture that enables the integration of 1 million qubits into a single cryostat - a milestone previously thought impossible. This breakthrough dramatically reduces the size, energy consumption, and cost of quantum computers, unlocking practical applications across pharmaceuticals, AI, materials science, and energy.

Funding is led by Viola Ventures and Earth & Beyond Ventures.

The biggest obstacle to building a commercially viable superconducting quantum computer has been managing heat, given that systems rely on delicate quantum processors that must operate at temperatures near absolute zero. Traditional control electronics generate too much heat and must therefore be placed outside the cryostat (the ultra-cold chamber where quantum computing happens). This separation creates an insurmountable scaling bottleneck, requiring millions of cables to connect the control electronics to the processor.

Right now, the most advanced quantum computers from IBM and Google can only fit about 5,000 qubits per cryostat, requiring hundreds of interconnected cryostats in a football-field-sized facility to scale. This approach is not only space- and cost-prohibitive but also introduces complexity that hinders practical adoption. QuamCore's breakthrough changes this entirely, reducing cabling by a factor of more than 1,000, enabling the first practical path to scaling beyond 1 million qubits in a single, compact system. What once required a football field of hardware can now, with QuamCore's technology, be condensed into a compact box - fundamentally reshaping the economics and accessibility of quantum computing.

QuamCore's leadership team brings together deep expertise in quantum physics, superconducting systems, and large-scale semiconductor development.
CEO Alon Cohen, co-founder of the EyeC Radar Group at Mobileye (Intel), served as the chief architect and head of the EyeC Radar algorithm group, shaping it into a core technology for autonomous vehicle perception. He holds over 40 patents in radar, communication, and signal processing and was awarded Intel's highest innovation honor, the Intel Oscar Prize, for his contributions.

CTO Prof. Shay Hacohen-Gourgy, a leading expert in superconducting quantum computing, has spent over 15 years pioneering experimental research in quantum information and solid-state physics. A professor at the Technion – Israel Institute of Technology, his groundbreaking work in superconducting circuits and quantum measurement has been published in top-tier journals, including Nature. 
Chief scientist Prof. Serge Rosenblum, a leading researcher at the Weizmann Institute of Science, brings over 15 years of experience across various quantum technologies, with multiple breakthrough papers published in top-tier journals, including Science.
Prof. Hacohen-Gourgy and Prof. Rosenblum conducted their postdoctoral research at UC Berkeley and Yale before returning to Israel seven years ago. They built Israel's leading superconducting quantum laboratories at the Weizmann Institute and the Technion, respectively.
Senior Advisor Prof. Eby G. Friedman, a world-renowned expert in superconducting digital circuits from the University of Rochester, has contributed to over 600 publications and patents, with his work laying the foundation for advances in high-performance digital superconducting logic.

"The challenge in quantum computing isn't just adding more qubits - it's how you scale without hitting fundamental barriers," said Alon Cohen, CEO of QuamCore. "From the outset, we understood that reaching 1 million qubits was the threshold for unlocking real-world value. But we also saw that this required a radical rethinking of quantum processor architecture. We explored multiple approaches and found a path that actually works - one that eliminates the core bottleneck preventing quantum computing from scaling."

"To achieve this, we rethought everything - from transitioning to digital control, developing new superconducting devices, and redesigning the processor architecture from the ground up," Cohen added. "The result is a breakthrough in power efficiency, overcoming a fundamental gap that has long prevented large-scale quantum computing. Today, we have a detailed blueprint for a 1-million-qubit quantum computer in a single cryostat, marking a clear, viable path toward practical large-scale quantum computing. Our design also incorporates built-in error correction, paving the way for fault-tolerant quantum systems."

"The world is still waiting for a commercially viable quantum computer, and no one has had a clear path to get there - until now," said Zvika Orron, General Partner at Viola Ventures. "QuamCore's breakthrough isn't just about making quantum computers smaller; it's about enabling large-scale, fault-tolerant quantum computing for the first time. Just as transistors replaced vacuum tubes, QuamCore is redefining what's possible in quantum."
