QUDORAClient

class QUDORAClient

Bases: QuantumBaseClient[AlgoType, _QudoraJobMeta, QiskitCircuit]

Client that executes quantum circuits on QUDORA hardware.

Connects to the QUDORA platform using an API token and runs circuits on the specified device. Accepts any algorithm conforming to QuantumAlgoProtocol via the algo parameter.

Methods

__init__	Initialize a QUDORAClient.
solve	Call the solver service to solve the given optimization problem.
version	Return the installed qudora_sdk package version.

Attributes

acceptable_degrees	Polynomial degrees accepted by the algorithm for the objective and constraints.
algo	The algorithm class used by this client.
device	Name of the target QUDORA device.
device_settings	Device-specific settings forwarded to the QUDORA backend on each job submission.
qiskit_pass_manager	Qiskit transpilation pass manager.
token	QUDORA API token used to authenticate, or None if not set.
url	QUDORA service URL, or None to use the default endpoint.
parameters	Algorithm parameters instance.

__init__(

algo: type[AlgoType],

token: str | None = None,

url: str | None = None,

device: str = 'Qamelion',

qiskit_pass_manager: PassManager | EllipsisType | None = Ellipsis,

device_settings: dict | None = None,

) → None

Initialize a QUDORAClient.

Parameters:

• algo (type[AlgoType]) – The algorithm class to use (e.g., QAOA).

• token (str | None) – QUDORA API token. Required to access the service.

• url (str | None) – QUDORA service URL. If None, the default endpoint is selected automatically based on the token prefix.

• device (str) – Name of the QUDORA device. Defaults to "Qamelion".

• qiskit_pass_manager (PassManager | EllipsisType | None) – Custom Qiskit transpilation pass manager. If ... (default), a preset pass manager is generated automatically. Pass None to skip transpilation.

• device_settings (dict | None) – Device-specific settings forwarded to the QUDORA backend on each job submission.

solve(objective: Poly | Matrix, constraints: ConstraintList | None, dry_run: bool = False) → CustomClientResultProtocol | None

Call the solver service to solve the given optimization problem.

Parameters:

• objective (Poly | Matrix) – The objective function to minimize.

• constraints (ConstraintList | None) – Constraints for the problem. If None, no constraints are applied.

• dry_run (bool) – If True, validate inputs without executing circuits and return None.

Returns:

The algorithm result, or None if dry_run is True.

Return type:

CustomClientResultProtocol | None

version() → str

Return the installed qudora_sdk package version.

property acceptable_degrees: AcceptableDegrees

Polynomial degrees accepted by the algorithm for the objective and constraints.

property algo: type[AlgoType]

The algorithm class used by this client.

property device: str

Name of the target QUDORA device.

property device_settings: dict | None

Device-specific settings forwarded to the QUDORA backend on each job submission.

parameters

Algorithm parameters instance. The concrete type depends on the algorithm; for QAOA this is QAOA.Parameters. Modify this to configure the algorithm before calling solve().

property qiskit_pass_manager: PassManager | EllipsisType | None

Qiskit transpilation pass manager.

... (default) generates a preset pass manager automatically; None skips transpilation.

property token: str | None

QUDORA API token used to authenticate, or None if not set.

property url: str | None

QUDORA service URL, or None to use the default endpoint.
