Quantinuum scales quantum error correction well beyond breakeven

Quantinuum said its current trapped-ion hardware, Helios, scales logical qubits well beyond the breakeven point, with each step up in code distance cutting error rates by more than a factor of 10. It built distance-3, 5 and 7 color codes using 13, 37 and 73 hardware qubits and suppressed leakage errors by 6.5x.

• Each step up in logical qubit distance cuts errors by more than 10x
• Distance-3, 5 and 7 codes used 13, 37 and 73 hardware qubits
• Laser-based scheme suppresses leakage errors by a factor of 6.5
• Helios can entangle any two ions, supporting essentially any error code
