qoolqit.register

source module qoolqit.register

Classes

• Register — The Register in QoolQit, representing a set of qubits with coordinates.

source class Register(qubits: dict)

The Register in QoolQit, representing a set of qubits with coordinates.

Default constructor for the Register.

Parameters

• qubits : dict — a dictionary of qubits and respective coordinates {q: (x, y), ...}.

Attributes

• qubits : dict — Returns the dictionary of qubits and respective coordinates.

• qubits_ids : list — Returns the qubit keys.

• n_qubits : int — Number of qubits in the Register.

Methods

• from_graph — Initializes a Register from a graph that has coordinates.

• from_coordinates — Initializes a Register from a list of coordinates.

• distances — Distance between each qubit pair.

• min_distance — Minimum distance between all qubit pairs.

• interactions — Interaction 1/r^6 between each qubit pair.

• draw — Draw the register.

source classmethod Register.from_graph(graph: DataGraph) → Register

Parameters

• graph : DataGraph — a DataGraph instance.

Raises

• ValueError

source classmethod Register.from_coordinates(coords: list) → Register

Initializes a Register from a list of coordinates.

Parameters

• coords : list — a list of coordinates [(x, y), ...]

Raises

• TypeError
