Quantum X Labs claims fewer decoding failures in tests using IBM processor data

Published Monday, November 9, 2026 · 10:07 AM EST

Quantum X Labs said preliminary benchmarks using experimental data from three IBM quantum processors showed up to 20% fewer logical decoding failures. The company expanded its quantum error correction program to IBM Fez, IBM Kingston and IBM Pittsburgh after earlier work with datasets generated by Google quantum hardware. Its workflow combines experimental measurements, calibration of models of processor noise, GPU-accelerated AI training and decoder evaluation. The calibration helps decoders identify and correct errors during quantum computations. The results concern preliminary tests on processor datasets; use of IBM's names does not imply affiliation or endorsement.
