cirq_google.optimizers.ConvertToXmonGates

Attempts to convert strange gates into XmonGates.

First, checks if the given operation is already a native xmon operation.

Second, checks if the operation has a known unitary. If so, and the gate is a 1-qubit or 2-qubit gate, then performs circuit synthesis of the operation.

Third, attempts to cirq.decompose to the operation.

Fourth, if ignore_failures is set, gives up and returns the gate unchanged. Otherwise raises a TypeError.

ignore_failures If set, gates that fail to convert are forwarded unchanged. If not set, conversion failures raise a TypeError.

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.
