cirq_rigetti.aspen_device.AspenQubit

THIS CLASS IS DEPRECATED.

Inherits From: OctagonalQubit

cirq_rigetti.aspen_device.AspenQubit(
    octagon: int, octagon_position: int
)

IT WILL BE REMOVED IN cirq v1.6.

Cirq-Rigetti is deprecated. For more details or to provide feedback see https://github.com/quantumlib/Cirq/issues/7058

octagon_position Position within octagon, indexed as pictured above.

ValueError If the position specified is greater than 7.

dimension Returns the dimension or the number of quantum levels this qid has. E.g. 2 for a qubit, 3 for a qutrit, etc.
octagon

octagon_position

x Returns the horizontal position of the qubit, assuming each side of the octagon has length 1.
y Returns the vertical position of the qubit, assuming each side of the octagon has length 1. The y-axis is oriented downwards.
z Because this is a 2-dimensional qubit, this will always be 0.

Methods

distance

View source

distance(
    other: cirq.Qid
) -> float

Returns the distance between two qubits.

Args
other An AspenQubit to which we are measuring distance.

Returns
The distance between two qubits.

Raises
TypeError other qubit must be AspenQubit.

from_aspen_index

View source

@staticmethod
from_aspen_index(
    index: int
) -> 'AspenQubit'

Initializes an AspenQubit at the given index. See OctagonalQubit to understand OctagonalQubit indexing.

Args
index The index at which to initialize the AspenQubit.

Returns
The AspenQubit with requested index.

Raises
ValueError index is not a valid octagon position.

from_grid_qubit

View source

@staticmethod
from_grid_qubit(
    grid_qubit: cirq.GridQubit
) -> 'AspenQubit'

Converts cirq.GridQubit to AspenQubit.

Returns
The equivalent AspenQubit.

Raises
ValueError GridQubit cannot be converted to AspenQubit.

from_named_qubit

View source

@staticmethod
from_named_qubit(
    qubit: cirq.NamedQubit
) -> 'AspenQubit'

Converts cirq.NamedQubit to AspenQubit.

Returns
The equivalent AspenQubit.

Raises
ValueError NamedQubit cannot be converted to AspenQubit.
UnsupportedQubit If the supplied qubit is not a named qubit with an octagonal index.

to_grid_qubit

View source

to_grid_qubit() -> cirq.GridQubit

Converts AspenQubit to cirq.GridQubit.

Returns
The equivalent GridQubit.

Raises
ValueError AspenQubit cannot be converted to GridQubit.

to_named_qubit

View source

to_named_qubit() -> cirq.NamedQubit

Converts AspenQubit to cirq.NamedQubit.

Returns
The equivalent NamedQubit.

validate_dimension

@staticmethod
validate_dimension(
    dimension: int
) -> None

Raises an exception if dimension is not positive.

Raises
ValueError dimension is not positive.

with_dimension

with_dimension(
    dimension: int
) -> 'Qid'

Returns a new qid with a different dimension.

Child classes can override. Wraps the qubit object by default.

Args
dimension The new dimension or number of levels.

__le__(
    other
)

Return self<=value.

__lt__

__lt__(
    other
)

Return self<value.

__ne__

__ne__(
    other
)

Return self!=value.
