TNO Quantum: Optimization - QUBO - Components

TNO Quantum provides generic software components aimed at facilitating the development of quantum applications.

This package contains the components to define QUBOs and solvers.

Documentation

Documentation of the tno.quantum.optimization.qubo.components package can be found here.

Install

Easily install the tno.quantum.optimization.qubo.components package using pip:

$ python -m pip install tno.quantum.optimization.qubo.components

Usage

The QUBO Components package can be used to define custom solver classes as shown in the following example.

from tno.quantum.optimization.qubo.components import QUBO, Solver, BasicResult

class CustomSolver(Solver[BasicResult]):
   def _solve(self, qubo: QUBO) -> BasicResult:
      result = ... # solve QUBO and construct result
      return result

The example below shows how to obtain all installed solvers.

An instance of a solver can be obtained via the get_instance() function on an SolverConfig instance.

Note: the "simulated_annealing_solver" solver shown in the example requires tno.quantum.optimization.qubo.solvers to be installed.

from tno.quantum.optimization.qubo.components import SolverConfig

supported_solvers = SolverConfig.supported_items()

solver_config = SolverConfig(name="simulated_annealing_solver", options={})
solver = solver_config.get_instance()
