.. start_cloud_about
D-Wave Cloud Client is a minimal implementation of the REST interface used to communicate with D-Wave Sampler API (SAPI) servers.
SAPI is an application layer built to provide resource discovery, permissions, and scheduling for quantum annealing resources at D-Wave Systems. This package provides a minimal Python interface to that layer without compromising the quality of interactions and workflow.
The example below instantiates a D-Wave Cloud Client and solver based on the local system's auto-detected default configuration file and samples a random Ising problem tailored to fit the solver's graph.
.. code-block:: python
import random
from dwave.cloud import Client
# Connect using the default or environment connection information
with Client.from_config() as client:
# Load the default solver
solver = client.get_solver()
# Build a random Ising model to exactly fit the graph the solver supports
linear = {index: random.choice([-1, 1]) for index in solver.nodes}
quad = {key: random.choice([-1, 1]) for key in solver.undirected_edges}
# Send the problem for sampling, include solver-specific parameter 'num_reads'
computation = solver.sample_ising(linear, quad, num_reads=100)
# Print the first sample out of a hundred
print(computation.samples[0])
