From: Parallel window decoding enables scalable fault tolerant quantum computation

Fig. 1

In fault-tolerant implementations with logical qubits, the logical Z measurement must be decoded before the S correction can be correctly applied. This leads to a response time τ that is largely determined by the decoding time but also includes communication and control latency.
