156-Qubit Experiment Tests Repeated Feedback to Restore Order

Repeating operations and check-and-reset steps

According to the report, researchers connected as many as 100 qubits at once in a 156-qubit processor. They alternated scrambling operations with checks and resets, carrying out nearly 5,000 qubit operations and almost 5,000 checks and resets. The report says the system returned to order when resetting and checking exceeded half of all operations.

The supplied report does not provide a like-for-like benchmark against an earlier experiment.

The reported experiment found that order resumed when checks and resets accounted for more than half of operations, while testing repeated feedback across a large quantum system.

The work reportedly tests repeated, real-time feedback rather than a one-off correction. It remains a stress test that would need to scale up and use more complex rules before serving practical fault-tolerant quantum computing.
