log_meas(model, layout, detectors, rot_basis=False, anc_reset=True, anc_detectors=None)

Returns stim circuit corresponding to a logical measurement of the given model. It defines the observables for all the logical qubits in the layout.

Parameters:

model

Noise model for the gates.

layout

Code layout.

detectors

Detector definitions to use.

rot_basis

If True, the memory experiment is performed in the X basis. If False, the memory experiment is performed in the Z basis. By deafult False.

anc_reset

If True, ancillas are reset at the beginning of the QEC round. By default True.

anc_detectors

List of ancilla qubits for which to define the detectors. If None, adds all detectors. By default None.

Notes

It activates all the ancillas in detectors to always build the detectors. As this function should not be used when building encoded circuits with the iterating functions, it does not matter if the detectors are activated or not.
