QuamCore Ltd has successfully secured $26 million in a Series A funding round to advance its goal of building a groundbreaking quantum computer featuring one million qubits. This investment, led by Sentinel Global and supported by Arkin Capital along with several existing investors, elevates QuamCore’s total external funding to $35 million.
Currently, the largest operational quantum chips fall short of 1,500 qubits, limiting their computational power. A significant challenge in scaling these systems is the reliance on cryogenic refrigerators, which not only restrict space but also necessitate extensive cabling to connect qubits to external control systems. The intricate setup often hampers efforts to increase qubit numbers.
QuamCore, based in Tel Aviv, has introduced an innovative quantum computer architecture designed to significantly minimize the cabling demands, claiming to cut them by over 1,000 times. The company asserts that its technology allows for the integration of one million qubits into a single cryogenic system, with the architecture already fully designed and simulated.
Typically, a quantum computer’s qubits utilize a control chip that operates outside the refrigeration unit. By embedding qubit control components within the fridge itself, QuamCore aims to streamline data transmission, enhancing operational efficiency.
In parallel, Intel Corp. has adopted a similar strategy with its Pando Tree device, which incorporates a qubit control chip within the cryogenic environment, thereby reducing cabling needs by bringing control closer to the source.
QuamCore’s approach utilizes superconducting materials for its qubits, allowing for compatibility with conventional chip manufacturing techniques. This not only cuts production costs but also enhances speed in processing tasks compared to other quantum circuit variants.
“Our objective was to fundamentally rethink the architecture of superconducting qubits, the most advanced platform available. This has culminated in a scalable and compact design that aligns well with the trajectory of the industry,” stated QuamCore CEO Alon Cohen.
The freshly acquired funds will facilitate the production of QuamCore’s first-generation quantum chips and support the establishment of a new quantum laboratory focusing on research initiatives.
