Breakthrough removes a major bottleneck in fault-tolerant quantum computing, enabling real-time error correction across millions of operations without slowing down execution time.

COLLEGE PARK, Md.--(BUSINESS WIRE)-- IonQ (NYSE: IONQ), the worlds leading full-stack quantum platform and foundry, today announced a major milestone in fault-tolerant quantum computing. Researchers demonstrated the development and successful testing of the industrys first end-to-end real-time quantum error correction decoder that runs on a single standard off-the-shelf central processing unit (CPU).

Quantum error correction is essential for building practical, fault-tolerant quantum computers because physical qubits... More
