QuamCore sets 1M-Qubit quantum computer in a single cryostat
Israeli deep-tech startup QuamCore received $26 million to build a million-qubit quantum computer in a cryostat.
Series A funding
After receiving $26 million (£20.6 million) in Series A funding, Israeli deep-tech startup QuamCore raised $35 million (£27.8 million). QuamCore hopes to develop the first one-million-qubit quantum computer inside a cryostat with the funds.
This large investment supports QuamCore's ambition of developing the world's first 1-million-qubit quantum computer in a cryostat.
Sentinel Global led the Series A investment, with Arkin Capital, returning investors Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, and Quantum Leap (or Qbeat Ventures) contributing. The Israel Innovation Authority's $4 million non-dilutive funding showed national interest in the startup's potential.
Addressing Quantum Computing Scalability
Quantum computing could revolutionise medicine, energy, AI, and materials. However, the limited scalability of most quantum devices has prevented wider use. Most platforms from Google and IBM have a 5,000-qubit limit, requiring expensive and complex multi-cryostat infrastructures for larger systems.
QuamCore's groundbreaking discovery created superconducting qubits, quantum computing's most advanced and cost-effective platform. The business plans to integrate superconducting digital control logic into the cryostat. This novel design eliminates the key heat bottleneck that has hindered quantum technology's broad deployment and decreases cabling by over 1,000. This integration places control components on the same circuit board as qubits.
Fault-Tolerant Quantum Computing Roadmap
Quantum error correction is essential to QuamCore's mechanism. Preventing data loss and instability from environmental interference and noise is essential for commercially viable, fault-tolerant quantum computers.
QuamCore CEO Alon Cohen said it focused on the minimal viable system to unlock real-world quantum advantage from the start: 1 million qubits. He added, “It decided to drastically rethink the architecture of the most advanced and effective platform: superconducting qubits. A plan that can develop, stay small, and follow industry trends is the result.
Impact on Quantum Economics
Revolutionary effects are expected by investors. Dror Sharon, Partner at Sentinel Global, said QuamCore's team has built a feasible, scalable roadmap to a million-qubit computer using superconducting technology, quantum's most cutting-edge and economically attractive platform. QuamCore "removes the thermal bottleneck that throttles today's systems and charts a credible path to a single-cryostat, million-qubit machine" by incorporating control logic into the cryostat, said Arkin Capital CEO Nir Arkin. It expects this density to open trillion-dollar marketplaces and redefine quantum economics.
Design to Build QuamCore plans to use the new funds to build and simulate its first-generation quantum processors and manufacture them. The company also aims to expand its workforce and operations and create a quantum lab. Cohen added that this investment speeds prototype integration and chip manufacture. Superconducting qubits will lead the maturing quantum industry strategy.
