Israeli quantum computing firm QuamCore has secured $9 million in seed funding.

Though it was founded in 2022, the company only emerged from stealth this week and with a patented architecture it claims will enable the integration of one million qubits into a single cryostat.

The funding was led by Viola Ventures and Earth & Beyond Ventures.

Though the qubits they create can exist in multiple forms, supercooled quantum computers face physical limitations around how many atoms the systems can physically cool within one fridge (also known as a crytostat). QuamCore claims its approach can overcome these physical limits.

Few details on how the company aims to achieve this have been shared.

QuamCore CEO Alon Cohen was previously co-founder of the EyeC Radar Group at Mobileye (later acquired by Intel).

"The challenge in quantum computing isn’t just adding more qubits - it’s how you scale without hitting fundamental barriers," said Cohen. "From the outset, we understood that reaching one 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."

He continued: “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.”

Viola Ventures is part of Viola Group, Israel’s leading tech investment platform, managing over $6.5bn AUM. Founded in 2000, the venture company has invested in more than 200 companies.

"The world is still waiting for a commercially viable quantum computer, and no one has had a clear path to get there - until now," added 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."

On its website, QuamCore's list of partners includes the Israel Innovation Authority, Axess Ventures, Qbeat Ventures, Rhodium Family Ventures, IDA Ventures, and Surround Ventures.
