cirq_google.serialization.CircuitOpSerializer

Describes how to serialize CircuitOperations.

Inherits From: OpSerializer

can_serialize_predicate The method used to determine if this can serialize an operation.

Depending on the serializer, additional checks may be required.

internal_type Returns the type that the operation contains.

For GateOperations, this is the gate type. For CircuitOperations, this is FrozenCircuit.

serialized_id Returns the string identifier for the resulting serialized object.

This ID denotes the serialization format this serializer produces. For example, one of the common serializers assigns the id 'xy' to XPowGates, as they serialize into a format also used by YPowGates.

Methods

can_serialize_operation

View source

can_serialize_operation(
    op: cirq.Operation
) -> bool

Whether the given operation can be serialized by this serializer.

to_proto

View source

to_proto(
    op: cirq.CircuitOperation,
    msg: Optional[cirq_google.api.v2.program_pb2.CircuitOperation] = None,
    *,
    arg_function_language: Optional[str] = '',
    constants: List[cirq_google.api.v2.program_pb2.Constant],
    raw_constants: Dict[Any, int]
) -> cirq_google.api.v2.program_pb2.CircuitOperation

Returns the cirq.google.api.v2.CircuitOperation message as a proto dict.

Note that this function requires constants and raw_constants to be pre-populated with the circuit in op.
