source module mis.pipeline.basesolver

Shared definitions for solvers.

This module is useful mostly for users interested in writing new solvers.

Classes

• BaseSolver — Abstract base class for all solvers (quantum or classical).

source class BaseSolver(instance: MISInstance, config: SolverConfig)

Bases : ABC

Abstract base class for all solvers (quantum or classical).

Provides the interface for solving, embedding, pulse shaping, and execution of MISproblems.

The BaseSolver also provides a method to execute the Pulse and Register

Initialize the solver with the MISinstance and configuration.

Parameters

• instance : MISInstance — The MISproblem to solve.

• config : SolverConfig — Configuration settings for the solver.

Methods

• solve — Solve the given MISinstance.

• embedding — Generate or retrieve an embedding for the instance.

• pulse — Generate a pulse schedule for the quantum device based on the embedding.

• detuning — Return detunings to be executed alongside the pulses.

source method BaseSolver.solve() → list[MISSolution]

Solve the given MISinstance.

Parameters

• instance — if None (default), use the original instance passed during

• initialization. Otherwise, pass a custom instance. Used e.g. for

• preprocessing.

Returns

• list[MISSolution] — A list of solutions, ranked from best (lowest energy) to worst (highest energy).

source method BaseSolver.embedding() → Register

Generate or retrieve an embedding for the instance.

Returns

• dict — Embedding information for the instance.

source method BaseSolver.pulse(embedding: Register) → Pulse

Generate a pulse schedule for the quantum device based on the embedding.

Parameters

• embedding : Register — Embedding information.

Returns

• Pulse — Pulse schedule.

source method BaseSolver.detuning(embedding: Register) → list[Detuning]

Return detunings to be executed alongside the pulses.

Parameters

• embedding : Register — Embedding information.

Returns

• list[Detuning] — The list of detunings.
