ChipLayout#

Module: exa.common.qcm_data.chip_layout

class ChipLayout(qubits, couplers, computational_resonators, qubits_without_probeline=None, angles=None)#

Bases: object

The chip layout contains the components, their 2D cartesian coordinates, and their angles.

The subset of qubits without any probe lines, which appears in certain constellation-type chips, are stored in the additional attribute qubits_without_probeline.

The angle is assumed to lie between the positive x-axis and the orientation vector of the component and measured in degrees.

Parameters:

qubits (dict[str, tuple[float, float]]) – Dictionary of qubit names mapped to their 2d coordinates
couplers (dict[str, tuple[float, float]]) – Dictionary of coupler names mapped to their 2d coordinates
computational_resonators (dict[str, tuple[float, float]]) – Dictionary of computational resonators names mapped to their 2d coordinates
qubits_without_probeline (Iterable[str] | None) – Iterable of qubits without a probeline
angles (dict[str, float] | None) – Dictionary of component names mapped to their 2d coordinates

`get_all_qubit_angles`	Get the angles for all qubits.
`get_all_qubit_coordinates`	Get the coordinates for all qubits.
`get_angle`	Get the angle for the given component.
`get_coordinates`	Get the coordinates for the given component.

classmethod from_chip_design_record(record)#

Construct the chip layout from a raw chip design record.

Parameters:: record (dict) – The chip design record as returned by station control.
Returns:: The corresponding chip layout.
Return type:: ChipLayout

normalize_coordinates(min_spacing)#

Rescale component coordinates

Rescale all component coordinates so that the minimum distance between 2 components is min_spacing

Parameters:: min_spacing (float)
Return type:: None

rotate_layout(angle=45)#

Clockwise rotation of coordinates.

Parameters:: angle (float)
Return type:: None

move_origin()#

Changes the origin of the Cartesian coordinate system such that all elements move into the first quadrant.

If there is a component with coordinates (x_min, y_min) it will move to (0, 0).

Return type:: None

get_coordinates(component)#

Get the coordinates for the given component.

Parameters:: component (str) – The name of the component.
Returns:: The 2D cartesian coordinates.
Return type:: tuple[float, float]

get_all_qubit_coordinates()#

Get the coordinates for all qubits.

Return type:: dict[str, tuple[float, float]]

get_angle(component)#

Get the angle for the given component.

Parameters:: component (str) – The name of the component.
Returns:: The angle of the component.
Return type:: float

get_all_qubit_angles()#

Get the angles for all qubits.

Return type:: dict[str, float]
