At Quantinuum, we’ve already demonstrated numerous QEC codes, all the primitives needed for logical computation, steadily declining logical error rates, and full computations at the logical level.
This logical error rate is ten times lower than our September record and more than 100 times lower than the record achieved on a superconducting system.
This nearly “six nines” result sets a new record for logical accuracy through quantum error correction.
Comparing at the same code distance, the previous best demonstrated error rate was using a surface code.
The white circles represent physical qubits, and the animation shows how logical qubits are formed at color code distances of 3, 5, and 7.
