IonQ Cracks Quantum Error Correction with Real-Time Quantum Decoder
The test covered 408 logical qubits and more than 31.5 million operations, IonQ said, as it works toward practical fault-tolerant quantum computing.
- On Tuesday, Maryland-headquartered IonQ announced a new real-time quantum error decoder that runs on a single CPU, allowing quantum computers to fix errors continuously without pausing operations.
- Quantum error correction typically creates a bottleneck where computation pauses to rectify errors, but IonQ's architecture processes syndrome measurements and corrections efficiently on standard hardware.
- During the evaluation, 408 logical qubits across 88 memory blocks executed more than 31.5 million individual quantum operations, with the decoder adding only 0.02 percent to the total computation.
- Shares of IonQ surged Wednesday, gaining as much as 15% in premarket trading, while Rigetti Computing and D-Wave rose more than 4% ahead of the open.
- The company plans to build a quantum computer with 256 physical qubits for industrial-scale usage; "Empirical evidence like this supports our vision for fault tolerance," added Jon Gable, Vice President at IonQ Architecture.
