Solver Retirement - Advantage_system1.1

On November 5th, 2021 at 10:00 PT the Advantage_system1.1 solver will be removed from Leap. Historical data for problems submitted to this solver will continue to be accessible through the API. The new Advantage_system4.1 solver will remain online as the primary Advantage solver. Hybrid solvers (BQM, DQM, and CQM) will not be affected by this change.

Note that Advantage_system1.1 and Advantage_system4.1 have different physical properties such as annealing schedule and working graph (number and arrangement of active qubits). If your code is dependent on any of these low-level parameters, you can check the QPU-specific physical properties documents.

Code that references the Advantage_system1.1 solver by name can be updated by using feature-based solver selection. For example, this sampler setup would change from:

sampler = DWaveSampler(solver='Advantage_system1.1')


sampler = DWaveSampler(solver={'qpu': True})
