A Walking Code Removed Leakage Without Extra Rounds
Two honeycomb schedules periodically cleared leaked qubits while preserving distance to Pauli errors in simulation.
Summary
Two honeycomb schedules periodically cleared leaked qubits while preserving distance to Pauli errors in simulation.
The swirling and sliding honeycomb Floquet circuits move the protected code while periodic measurements remove qubit leakage. Unlike earlier dynamic honeycomb schedules, the designs preserve distance to ordinary Pauli errors and add no separate leakage-reduction cycle. Simulations under two leakage models found regimes where they corrected as many leakage errors as Pauli errors and could outperform the same-distance walking surface code. The evidence is numerical and depends on the chosen noise models.
