Methods

`CNOT`

CNOT(
    *args, **kwargs
)

A CZ conjugated by arbitrary single qubit Cliffords.

`CZ`

CZ(
    *args, **kwargs
)

A CZ conjugated by arbitrary single qubit Cliffords.

`controlled`

View source

controlled(
    num_controls: int = None,
    control_values: Optional[Sequence[Union[int, Collection[int]]]] = None,
    control_qid_shape: Optional[Tuple[int, ...]] = None
) -> "Gate"

Returns a controlled version of this gate. If no arguments are specified, defaults to a single qubit control.

num_controls: Total number of control qubits. control_values: For which control qubit values to apply the sub gate. A sequence of length num_controls where each entry is an integer (or set of integers) corresponding to the qubit value (or set of possible values) where that control is enabled. When all controls are enabled, the sub gate is applied. If unspecified, control values default to 1. control_qid_shape: The qid shape of the controls. A tuple of the expected dimension of each control qid. Defaults to (2,) * num_controls. Specify this argument when using qudits.

`num_qubits`

View source

num_qubits() -> int

The number of qubits this gate acts on.

`on`

View source

on(
    *qubits
) -> "Operation"

Returns an application of this gate to the given qubits.

Args
`*qubits`	The collection of qubits to potentially apply the gate to.

`qubit_index_to_equivalence_group_key`

View source

qubit_index_to_equivalence_group_key(
    index: int
) -> int

Returns a key that differs between non-interchangeable qubits.

`validate_args`

View source

validate_args(
    qubits: Sequence['cirq.Qid']
) -> None

Checks if this gate can be applied to the given qubits.

By default checks that:

inputs are of type Qid
len(qubits) == num_qubits()
qubit_i.dimension == qid_shape[i] for all qubits

Child classes can override. The child implementation should call super().validate_args(qubits) then do custom checks.

Args
`qubits`	The sequence of qubits to potentially apply the gate to.

Throws:

ValueError: The gate can't be applied to the qubits.
