Infleqtion (NYSE: INFQ), a Louisville, Colorado-based quantum computing firm, has announced a significant milestone in its development of the Sqale quantum platform. The company achieved 30 entangled logical qubits using 80 physical qubits, a feat it describes as the first demonstration of its kind by a neutral-atom quantum computing provider on a commercial system. This breakthrough represents a critical step toward Infleqtion’s longer-term roadmap, which includes reaching 100 logical qubits by 2028 and 1,000 by 2030.
The achievement stems from a co-design approach combining hardware and software innovations, including an AI-assisted discovery process that reduced the number of physical gates required for a key logical operation by half. Logical qubits, which group multiple physical qubits via software protocols, enhance computational stability and accuracy compared to individual physical qubits. The experiment was experimentally validated with a signal roughly 1,000 times stronger than underlying noise, executing approximately 1,000 physical operations.
Infleqtion’s Sqale quantum processing unit (QPU) and Superstaq software platform were central to this milestone. The company has already secured three customers for logical qubit circuits on the platform, including the Wellcome Leap Quantum for Bio program, where Infleqtion demonstrated a quantum neural network approach for biomarker discovery. Government entities such as the U.S. Department of War, NASA, and the U.K. government are also utilizing Infleqtion’s systems.
‘Getting 30 logical qubits to work together is hard, and our team has done it,’ Matt Kinsella, Infleqtion’s CEO, stated. ‘Co-design between our hardware and software enabled this demonstration with just 80 physical qubits.’ Pranav Gokhale, the company’s chief technology officer, highlighted the role of AI in discovering a new entangling operation that performs a critical function using half the physical gates previously required.
The achievement underscores Infleqtion’s progress in advancing neutral-atom quantum computing, positioning it as a key player in the evolving quantum computing ecosystem.
