qrmfold.depth_reducer module

qrmfold.depth_reducer.reduce_circuit_depth(circuit: Circuit)

Apply basic circuit depth reduction by accumulating commuting gates.

Currently supports I, S, Z, S_DAG, CZ, H, CX, TICK, and repeat blocks. Accumulates the S, Z, S_DAG, and CZ gates and removes the I gates.

Parameters:

circuit – Input circuit as a stim.Circuit.

Returns reduced_circuit:

An equivalent circuit of reduced depth as a stim.Circuit.

Raises:

ValueError – If an unsupported instruction is encountered.
