Optimal number of stabilizer measurement rounds in an idling surface code patch

Áron Márton and János K. Asbóth,

Quantum 9, 1767 (2025).

Logical qubits can be protected against environmental noise by encoding them into a highly entangled state of many physical qubits and actively intervening in the dynamics with stabilizer me…
