IonQ Shares Jump After Real-Time Quantum Error Decoder Test
The company says its decoder ran on a single standard CPU across hundreds of logical qubits and millions of operations.
IonQ shares rose more than 11% Wednesday after the quantum-computing company announced a successful test of what it called the industry’s first end-to-end real-time quantum error decoder, a development aimed at easing a major obstacle to practical quantum machines.
The stock gained as much as 15% in premarket trading before settling at a gain of more than 11%. The move would give IonQ its strongest session since Aug. 7, when the shares rose 11.8%, if it holds through the close.
IonQ said the decoder can identify, correct and process errors continuously while a quantum computer operates. The system ran on a single standard central processing unit and was tested across hundreds of logical qubits and more than millions of logical operations.
Quantum systems are highly sensitive to environmental noise, making error correction necessary for fault-tolerant computing. Earlier approaches could overwhelm the classical computers responsible for decoding those errors, creating delays.
“Successfully validating real-time decoding across hundreds of logical qubits and over millions of logical operations is an important milestone,” Nicolas Delfosse, IonQ’s quantum research lead, said in the company’s announcement. Other quantum-computing stocks, including Rigetti Computing, D-Wave and Quantum Computing, rose more than 4% before the U.S. market opened.
