QuamCore, a Tel Aviv–based deep-tech startup, has raised $26 million in Series A funding to advance its superconducting quantum computing architecture, bringing its total funding to $35 million. The round was led by Sentinel Global with participation from Arkin Capital, Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, and Quantum Leap, along with a $4 million non-dilutive grant from the Israel Innovation Authority.
QuamCore’s breakthrough lies in embedding ultra‑low‑power superconducting control logic directly inside the cryostat, removing the thermal bottlenecks and massive cabling requirements that limit today’s quantum machines. Current superconducting systems from companies such as IBM and Google typically top out at about 5,000 qubits per cryostat. QuamCore’s fully designed and simulated architecture claims scalability to 1 million qubits within a single cryostat, eliminating the need for complex multi‑cryostat deployments. The design incorporates built-in error correction, a critical step toward fault-tolerant, economically viable quantum computing.
The company was founded by a team of experts in quantum information, superconducting devices, and large-scale semiconductor systems. With its new funding, QuamCore plans to transition from design to fabrication of its first-generation processors, establish a dedicated quantum lab, and accelerate prototype integration. CEO Alon Cohen said the company’s “minimum viable system” target has always been 1 million qubits, positioning superconducting qubits as the leading platform for real-world quantum advantage in fields such as drug discovery, materials science, AI, and energy.
