IBM discusses the range of quantum error-correction techniques
ibm.com contains the excerpt below in a discussion related to Fault-tolerant quantum. Read the source for the surrounding context.
“A spectrum of error-correcting techniques is enabling useful quantum computation, measured not by logical qubits but by the circuits you can run with them.”
IBM company commentary about error-correction techniques and useful circuits, not proof that every fault-tolerance milestone has been reached.
QuEra puts a two-year horizon on useful quantum computing
QuEra's blog revisits its commercial chief Yuval Boger's forecast of useful quantum computation in about two years and the company's planned 2028 Libra delivery. It also acknowledges pushback about scaling.
“These are roadmap targets, not ratios already demonstrated in hardware at that scale.”
An ambitious company forecast, not a completed demonstration. A useful application still needs a credible comparison against classical methods.

Quantinuum reports Helix error-correction experiments on Helios
The company describes logical memory, logical computation, and entanglement across two error-correcting codes on its hardware. It presents these experiments as steps toward its planned Apollo system.
Company-reported component and architecture results. They do not establish a useful, large-scale universal quantum computer or that Apollo has been delivered.
