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).

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.

method
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).

method
embedding () → Register

Generate or retrieve an embedding for the instance.

Returns

  • dict — Embedding information for the instance.

method
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.

method
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.
