cirq.optimizers.ExpandComposite(
    no_decomp: Callable[[cirq.ops.Operation], bool] = (lambda _: False)
) -> None

IT WILL BE REMOVED IN cirq v1.0.

Use cirq.expand_composite instead.

An optimizer that expands composite operations via cirq.decompose.

For each operation in the circuit, this pass examines if the operation can
be decomposed. If it can be, the operation is cleared out and and replaced
with its decomposition using a fixed insertion strategy.

Args
no_decomp	A predicate that determines whether an operation should be decomposed or not. Defaults to decomposing everything.

Methods

optimization_at

View source

optimization_at(
    circuit: 'cirq.Circuit', index: int, op: 'cirq.Operation'
) -> Optional['cirq.PointOptimizationSummary']

Describes how to change operations near the given location.

For example, this method could realize that the given operation is an X gate and that in the very next moment there is a Z gate. It would indicate that they should be combined into a Y gate by returning PointOptimizationSummary(clear_span=2, clear_qubits=op.qubits, new_operations=cirq.Y(op.qubits[0]))

Args
circuit	The circuit to improve.
index	The index of the moment with the operation to focus on.
op	The operation to focus improvements upon.

Returns
A description of the optimization to perform, or else None if no change should be made.
