CHAD#

class CHAD(*, mask_set_name, variant, components)#

Bases: ImmutableBaseModel

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

Module: exa.common.qcm_data.chad_model

Attributes

`coupler_names`	Names of all the couplers declared in CHAD data.
`model_config`	Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
`probe_line_names`	Names of all the probe lines declared in CHAD data.
`qubit_names`	Names of all the qubits declared in CHAD data.
`mask_set_name`
`variant`
`components`

Methods

`filter_qubit_components`	Filter qubit components from the input components.
`get_common_coupler_for`	Convenience method for getting the name of a coupler connecting a pair of components.
`get_component`	Get component by component name.
`get_coupler_mapping_for`	Get the coupler-component mapping for the couplers that connects to at least two components
`get_probe_line_mapping_for`	Get the probe line-component mapping.
`get_probe_line_names_for`	Get probe lines for given qubits in CHAD data.
`group_components_per_default_operations`	Groups given qubits/couplers based on their defined default operations.

Parameters:

mask_set_name (str) –
variant (str) –
components (Components) –

get_component(component_name)#

Get component by component name.

Parameters:: component_name (str) –
Return type:: Component

property qubit_names: list[str]#: Names of all the qubits declared in CHAD data.

property coupler_names: list[str]#: Names of all the couplers declared in CHAD data.

property probe_line_names: list[str]#: Names of all the probe lines declared in CHAD data.

property computational_resonator_names: list[str]#: Names of all the computational resonators declared in CHAD data.

filter_qubit_components(component_names)#

Filter qubit components from the input components.

Parameters:: component_names (Collection[str]) –
Return type:: list[str]

get_probe_line_names_for(component_names)#

Get probe lines for given qubits in CHAD data.

Parameters:: component_names (Collection[str]) –
Return type:: list[str]

group_components_per_default_operations(component_names)#

Groups given qubits/couplers based on their defined default operations.

The default operations that can be deducted from a CHAD are readout, drive, and flux.

Parameters:

component_names (Collection[str]) – The component names to which to do the grouping. Other components present in the CHAD will not be included in the returned data.

Returns:

Tuple of qubits and couplers mapped to their connected default operations.
The data is in the form of a dict with the keys being readout, drive, and flux, and the values the list of component names having that particular operation.

Return type:

tuple[dict[str, list[str]], dict[str, list[str]]]

get_coupler_mapping_for(component_names)#

Get the coupler-component mapping for the couplers that connects to at least two components: in the given qubits.

Parameters:: component_names (Collection[str]) – The qubit names. May contain any number of qubits.
Returns:: Coupler names mapped to the components they connect.
Raises:: - ValueError – If the provided qubit name list contains duplicates.
Return type:: dict[str, list[str]]

get_probe_line_mapping_for(component_names)#

Get the probe line-component mapping.

Parameters:: component_names (Collection[str]) – The qubit names. May contain any number of qubits.
Return type:: dict[str, list[str]]

get_common_coupler_for(first_component, second_component)#

Convenience method for getting the name of a coupler connecting a pair of components.

Parameters:

first_component (str) – The name of the first component.
second_component (str) – The name of the second component. The order of qubits does not matter, i.e. the first_qubit and second_qubit arguments are interchangeable.

Returns:

The name of the coupler that connects the inputted components.

Raises:

- ValueError – If there were no couplers or more than one coupler connecting the component pair (the latter should not be possible in a realistic chip).

Return type:

str

model_config: ClassVar[ConfigDict] = {'frozen': True, 'ignored_types': (<class 'functools.cached_property'>,)}#: Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
