QuamCore, an Israel-based deep-tech startup tackling quantum computing\u2019s scalability challenges, has announced a USD 26\u202fmillion Series\u202fA, bringing total funding to USD 35\u202fmillion. 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 Qbeat. The Israel Innovation Authority contributed a USD 4\u202fmillion non-dilutive grant.<\/p>\n
QuamCore has developed a fully designed and simulated architecture capable of scaling to 1 million qubits\u00a0\u2014 in a single cryostat. This milestone fundamentally changes the economics of quantum computing by eliminating the need for massive multi-cryostat infrastructure, the company said in a media release.<\/p>\n
\u201cFrom day one, we focused on the minimum viable system to unlock real-world quantum advantage\u00a0\u2014 and that number is 1 million qubits,\u201d said Alon Cohen, CEO of QuamCore. \u201cWe 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.\u201d<\/p>\n
\u201cQuamCore\u2019s team has done what no one else has: built a practical, scalable roadmap to a million-qubit machine using superconducting technology \u2014 the most advanced and commercially promising platform in quantum today,\u201d said Dror Sharon, Partner at Sentinel Global. \u201cTheir architectural innovation is a leap forward, not just in hardware, but in how we think about scaling quantum systems in the real world.\u201d<\/p>\n
\u201cQuantum computing is now governed by scaling limits, not qubit fidelity. By embedding ultra\u2011low\u2011power superconducting control logic inside the cryostat, QuamCore removes the thermal bottleneck that throttles today\u2019s systems and charts a credible path to a single\u2011cryostat, million\u2011qubit machine,\u201d said Nir Arkin, CEO of Arkin Capital. \u201cThat density will rewrite quantum economics and unlock markets we expect to be worth trillions of dollars. We\u2019re proud to back this team.\u201d<\/p>\n
QuamCore\u2019s innovation lies in tightly integrating superconducting digital control logic directly into the cryostat. This 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, the media release said.<\/p>\n
With this funding, the company will move from design to fabrication of its first-generation processors, establish a dedicated quantum lab, and scale up operations.<\/p>\n
