cirq.StabilizerState

Interface for quantum stabilizer state representations.

This interface is used for CliffordTableau and StabilizerChForm quantum state representations, allowing simulators to act on them abstractly.

Methods

@abc.abstractmethod
apply_cx(
    control_axis: int,
    target_axis: int,
    exponent: float = 1,
    global_shift: float = 0
)

Apply a CX operation to the state.

Args
`control_axis`	The control axis of the operation.
`target_axis`	The axis to which the operation should be applied.
`exponent`	The exponent of the CX operation, must be an integer.
`global_shift`	The global phase shift of the raw operation, prior to exponentiation. Typically the value in `gate.global_shift`.

Raises
`ValueError`	If the exponent is not an integer.

@abc.abstractmethod
apply_cz(
    control_axis: int,
    target_axis: int,
    exponent: float = 1,
    global_shift: float = 0
)

Apply a CZ operation to the state.

Args
`control_axis`	The control axis of the operation.
`target_axis`	The axis to which the operation should be applied.
`exponent`	The exponent of the CZ operation, must be an integer.
`global_shift`	The global phase shift of the raw operation, prior to exponentiation. Typically the value in `gate.global_shift`.

Raises
`ValueError`	If the exponent is not an integer.

@abc.abstractmethod
