cirq.google.ConvertToSycamoreGates(
    tabulation: Optional[cirq.google.GateTabulation] = None,
    ignore_failures=False
) -> None

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

Methods

`convert`

View source

convert(
    op: cirq.ops.Operation
) -> List[cirq.ops.Operation]

`optimization_at`

View source

optimization_at(
    circuit, index, op
)

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.

`optimize_circuit`

optimize_circuit(
    circuit: cirq.circuits.Circuit
)

`call`

View source

__call__(
    circuit: cirq.circuits.Circuit
)

Call self as a function.
