A shared benchmark suite for logical qubits gets a first draft

Vendors publish incomparable numbers. A working group wants one protocol everyone can run.

Key takeaways

  • Protocol covers logical error rate, cycle time, and overhead together.
  • Results must include the decoder and its latency.
  • Reference implementation is public and runs on simulators.

Comparing quantum processors today means comparing marketing. Vendors report different metrics under different assumptions, and almost none of them include decoder latency.

A cross-institution working group has published a draft benchmark that reports logical error rate, cycle time, and physical overhead as one bundle, and requires disclosure of the decoder used.

A reference implementation runs against simulators, which lowers the barrier for smaller groups to publish comparable numbers.
