We give the Bacon-Shor code a threshold purely by deleting gates from its circuit. Specifically: we use lattice surgery to concatenate the Bacon-Shor code with itself using local planar connectivity, and observe that the resulting circuit is a subset of the circuit that would be used by a larger Bacon-Shor code.

  1. Comparison of spin-qubit architectures for quantum error-correcting codes

    quant-ph 2025-06 conditional novelty 6.0 of 10

    For distance-3 spin-qubit codes in silicon, a hybrid Loss-DiVincenzo/singlet-triplet encoding outperforms an all-Loss-DiVincenzo encoding, and the Bacon-Shor code gives much lower logical state-preparation error than ...

  2. Feasibility of Logical Bell State Generation in Memory Assisted Quantum Networks

    quant-ph 2024-12 conditional novelty 6.0 of 10

    Logical Bell-state protocols with d=3/5 surface and Bacon-Shor codes in ion traps need gate error rates around 10^-4 to 10^-5 to beat unencoded Bell states at 1 km, and the non-local protocol reaches about 33 Hz over ...

  3. Dynamical codes for hardware with noisy readouts

    quant-ph 2025-05 accept novelty 5.0 of 10

    Repeating measurement rounds in dynamically condensed colour codes substantially reduces teraquop volume under measurement-biased noise, while decoder choice determines whether XZ-only or XYZ schedules win.
