Thursday, 13 March 2025 | Israeli startup QuamCore claims to have developed a chip technology capable of powering a quantum computer with one million qubits. For comparison, Google’s recently introduced Willow processor contains 105 qubits, while IBM plans to unveil a 1,000-qubit machine this year.
Emerging to the public on Wednesday, QuamCore is presenting the results of a two-year study that led to the development of a new quantum processor architecture based on superconducting technology.
According to the company, its innovation compresses the number of qubits that would typically require massive computing facilities into a space the size of a few chips. The technology reportedly reduces power consumption, lowers costs and addresses a key industry challenge: computational errors.
For now, the technology exists only on paper. The first chips based on this architecture are expected to enter production soon at one of the world’s major semiconductor manufacturing plants. After production, the company plans to begin real-world testing.
The unveiling comes as QuamCore secures a US $9 million seed funding round led by Viola Ventures, with participation from Earth & Beyond, which invested in the company from its early stages, as well as Surround Ventures, strategic international investors and the Israel Innovation Authority.
“We founded the company with a single goal: solving the scaling problem that prevents quantum computers from being practical and useful,” QuamCore CEO and co-founder Alon Cohen told Ynetnews.
To perform the complex calculations expected of them, quantum computers must overcome computational errors and incorporate large numbers of qubits. “There’s not much you can do with a quantum computer below a million qubits,” he added.
Quantum processors using superconducting technology must operate near absolute zero. To achieve this, they are housed inside cryogenic cooling systems, with hundreds of gold wires connecting the chip—creating the characteristic “chandelier” appearance of quantum computers.
However, this approach hits a scalability limit of about 5,000 qubits, requiring massive cryogenic infrastructure to expand further.
How did QuamCore break past this barrier? Cohen explained that the company addressed a long-standing limitation: the need to position the control system outside the cooling chamber to prevent heat emissions.
Their new approach integrates a novel control system directly within the chamber, eliminating the need for thousands of external wires. This allows for significantly higher qubit density inside a single cryogenic unit.
Cohen claimed the breakthrough reduces computing costs and power consumption by a factor of 1,000, shortens construction time to just a few days and enables quantum computers to be networked together to increase qubit capacity further.
“We understood that real value comes from reaching a million qubits from day one. We’ve found a way to overcome the main bottleneck that has so far prevented this,” he said. “We have a detailed plan for a million-qubit quantum computer with built-in error correction—bringing us significantly closer to practical quantum systems capable of solving real-world problems.”
Founded in 2022, QuamCore’s leadership team includes experts in quantum physics, superconductors and chip development for communication systems.
CEO Alon Cohen, a former IDF intelligence Unit 8200 alumnus, has 25 years of experience in intelligence systems and communication chip development. He previously co-founded EyeC Radar at Mobileye, where he helped develop a 4D imaging system serving as a core sensor for Mobileye’s autonomous driving technology.
CTO Prof. Shai Hacohen-Gourgy is a leading expert in superconducting-based quantum computing with over 15 years of pioneering research in solid-state physics and experimental quantum information. A professor at Israel’s Technion, his work on superconducting circuits and quantum measurement has been published in top scientific journals, including Nature.
Chief scientist Prof. Serge Rosenblum, a researcher at the Weizmann Institute of Science, has over 15 years of experience in quantum technologies. His groundbreaking studies have been published in leading journals such as Science.
“This is a breakthrough that will enable large-scale quantum computing with built-in error correction,” Zvika Orron, a partner at Viola Ventures, said. “Just as transistors replaced vacuum tubes, QuamCore is redefining the future of the field. After extensive evaluation, we are convinced the potential here is unprecedented.”
