Quantinuum, the world’s largest integrated quantum computing company, has partnered with Microsoft to achieve a breakthrough in achieving fault-tolerant quantum computing by developing the most reliable logic qubits with active syndrome extraction demonstrated – an achievement that was previously thought to be years away from being realized.
A collaboration between the Quantinuum team in the US and UK and Microsoft’s quantum computing team has resulted in the creation of four logical qubits with error rates 800 times lower than the corresponding physical error rates. What is impressive is the team’s ability to flawlessly operate 14,000 independent instances of a quantum circuit. Breakthroughs of this magnitude have the potential to significantly accelerate progress toward the ultimate goal of universal, fault-tolerant quantum computing, which could shorten the time to solve real-world problems and revolutionize fields such as materials science and drug discovery.
Success relies on the industry-leading accuracy, scalability and flexibility of Quantinuum’s 32-qubit H2 quantum processor, powered by Honeywell, combined with Microsoft’s highly innovative error correction capabilities. The joint team created four logical qubits using 30 of the 32 physical qubits available on the H2, creating what both companies describe as the “most reliable logical qubits.” They also successfully demonstrated syndrome extraction another critical milestone necessary for fault-tolerant quantum computing.
“The results announced today solidify Quantinuum’s position at the forefront of universal, fault-tolerant quantum computing. Today’s performance was only possible with Quantinuum’s H2 quantum computer, which has unprecedented 99.8 percent two-qubit gate fidelity, as well as the 32 qubits in our QCCD architecture and the all-to-all qubit -Connectivity. Building on the exceptional performance of our current systems, we will continue to innovate to make universal, fault-tolerant quantum computing a reality faster than previously imaginable.” – Rajeeb Hazra , CEO, Quantinuum.
In the new era, which Microsoft calls “Level 2 Resilient,” quantum computing is able to deal with the problems caused by errors and can begin to address significant challenges such as modeling the states of molecules and materials, simulating systems in condensed matter physics, and exploring solutions to problems in many fields. Based on Microsoft’s demanding criteria, the demonstration of multiple entangled logical qubits that are superior to physical qubits marks a long-awaited transition into this second phase of quantum computing.
