An application of a gate to a sequence of qubits.
cirq.GateOperation( gate: 'cirq.Gate', qubits: Sequence['cirq.Qid'] ) -> None
Objects of this type are immutable.
||The gate to apply.|
||The qubits to operate on.|
||The classical controls gating this operation.|
||The gate applied by the operation.|
||The qubits targeted by the operation.|
||Returns a tuple of the operation's tags.|
||Returns the underlying operation without any tags.|
controlled_by( *control_qubits, control_values: Optional[Sequence[Union[int, Collection[int]]]] = None ) -> 'cirq.Operation'
Returns a controlled version of this operation. If no control_qubits are specified, returns self.
||Qubits to control the operation by. Required.|
For which control qubit values to apply the
operation. A sequence of the same length as
transform_qubits( qubit_map: Union[Dict['cirq.Qid', 'cirq.Qid'], Callable[['cirq.Qid'], 'cirq.Qid']] ) -> TSelf
Returns the same operation, but with different qubits.
||A function or a dict mapping each current qubit into a desired new qubit.|
|The receiving operation but with qubits transformed by the given function.|
||qubit_map was not a function or dict mapping qubits to qubits.|
validate_args( qubits: Sequence['cirq.Qid'] )
Raises an exception if the
qubits don't match this operation's qid
Call this method from a subclass's
||The new qids for the operation.|
||The operation had qids that don't match it's qid shape.|
with_classical_controls( *conditions ) -> 'cirq.ClassicallyControlledOperation'
Returns a classically controlled version of this operation.
An operation that is classically controlled is executed iff all conditions evaluate to True. Currently the only condition type is a measurement key. A measurement key evaluates to True iff any qubit in the corresponding measurement operation evaluated to a non-zero value.
The classical control will hide any tags on the existing operation, since tags are considered a local attribute.
||A list of measurement keys, strings that can be parsed into measurement keys, or sympy expressions where the free symbols are measurement key strings.|
with_gate( new_gate: 'cirq.Gate' ) -> 'cirq.Operation'
with_probability( probability: 'cirq.TParamVal' ) -> 'cirq.Operation'
with_qubits( *new_qubits ) -> TSelf
Returns the same operation, but applied to different qubits.
The new qubits to apply the operation to. The order must
exactly match the order of qubits returned from the operation's
with_tags( *new_tags ) -> 'cirq.Operation'
Creates a new TaggedOperation, with this op and the specified tags.
This method can be used to attach meta-data to specific operations without affecting their functionality. The intended usage is to attach classes intended for this purpose or strings to mark operations for specific usage that will be recognized by consumers. Specific examples include ignoring this operation in optimization passes, hardware-specific functionality, or circuit diagram customizability.
Tags can be a list of any type of object that is useful to identify this operation as long as the type is hashable. If you wish the resulting operation to be eventually serialized into JSON, you should also restrict the operation to be JSON serializable.
||The tags to wrap this operation in.|
without_classical_controls() -> 'cirq.Operation'
Removes all classical controls from the operation.
This function removes all classical controls gating the operation. It acts recursively, so that all classical control wrappers are always removed from the current operation.
If there are no classical controls on the operation, it will return
Since tags are considered local, this will also remove any tags from
the operation (unless there are no classical controls on it). If a
TaggedOperation is under all the classical control layers, that
TaggedOperation will be returned from this function.
|The operation with all classical controls removed.|
__eq__( other: _SupportsValueEquality ) -> bool
__mul__( other: Any ) -> Any
__pow__( exponent: Any ) -> 'cirq.Operation'
Raise gate to a power, then reapply to the same qubits.
Only works if the gate implements cirq.ExtrapolatableEffect. For extrapolatable gate G this means the following two are equivalent:
(G ** 1.5)(qubit) or G(qubit) ** 1.5
||The amount to scale the gate's effect by.|
|A new operation on the same qubits with the scaled gate.|
__rmul__( other: Any ) -> Any
