dwave-system 1.35.0

All things D-Wave System.

dwave-system

dwave-system is an API for easily incorporating D-Wave quantum computers as a sampler in the Ocean software stack, directly or through the Leap service’s cloud-based hybrid solvers. It includes DWaveSampler, a dimod sampler that accepts and passes system parameters such as system identification and authentication down the stack, StrideHybridSolver, for Leap’s Stride™ hybrid solver, and others. It also includes several useful composites—layers of pre- and post-processing—that can be used with DWaveSampler to handle minor-embedding, optimize chain strength, etc.

Installation

Installation from PyPI:

pip install dwave-system

Note

As of dwave-system 1.28.0, support for dwave-drivers is removed (it was used for calibration of qubits in chains via VirtualGraphComposite, but it’s no longer required due to improved calibration of newer QPUs).

Installation from source:

pip install -r requirements.txt
python setup.py install
