cirq.stratified_circuit

Repacks avoiding simultaneous operations with different classes.

cirq.stratified_circuit(
    circuit: 'cirq.AbstractCircuit',
    *,
    context: Optional['cirq.TransformerContext'] = None,
    categories: Iterable[Category] = ()
) -> 'cirq.Circuit'

This transforms the given circuit to ensure that no operations of different categories are found in the same moment. Makes no optimality guarantees. Tagged Operations marked with any of context.tags_to_ignore will be treated as a separate category will be left in their original moments without stratification.

circuit The circuit whose operations should be re-arranged. Will not be modified.
context cirq.TransformerContext storing common configurable options for transformers.
categories A list of classifiers picking out certain operations. There are several ways to specify a classifier. You can pass in a gate instance (e.g. cirq.X), a gate type (e.g. cirq.XPowGate), an operation instance (e.g. cirq.X(cirq.LineQubit(0))), an operation type (e.g.cirq.CircuitOperation), or an arbitrary operation predicate (e.g. lambda op: len(op.qubits) == 2).

A copy of the original circuit, but with re-arranged operations.
