QPUBackend

class pulser.backend.QPUBackend(sequence, connection, *, config=None)

Bases: RemoteBackend

Backend for sequence execution on a QPU.

Parameters:

sequence (Sequence) – A Sequence or a list of Sequences to execute on a backend accessible via a remote connection.
connection (RemoteConnection) – The remote connection through which the jobs are executed.
config (BackendConfig | None, default: None) – An optional backend configuration. For a QPU, it can be used to define a default_num_shots.

Methods

`open_batch`	Creates an open batch within a context manager object.
`run`	Runs the sequence on the remote QPU and returns the result.
`validate_job_params`	Validates a list of job parameters prior to submission.
`validate_sequence`	Validates a sequence prior to submission.

Signatures

open_batch()

Creates an open batch within a context manager object.

run(job_params=None, wait=False)

Runs the sequence on the remote QPU and returns the result.

Parameters:

job_params (list[JobParams] | None, default: None) – A list of dictionaries with the parameters to execute each job. If not given, the backend will attempt to run one job with ‘BackendConfig.default_num_shots’. If the sequence is parametrized, the values for all the variables necessary to build the sequence must be given in its own dictionary, for each job, under the ‘variables’ field. Each dictionary may contain a custom ‘runs’ field specifying the number of shots to take of the same sequence; if not given, ‘BackendConfig.default_num_shots’ is used when available.
wait (bool, default: False) – Whether to wait until the results of the jobs become available. If set to False, the call is non-blocking and the obtained results’ status can be checked using their status property.

Return type:

RemoteResults

Returns:

The results, which can be accessed once all sequences have been successfully executed.

static validate_job_params(job_params, max_runs)

Validates a list of job parameters prior to submission.

static validate_sequence(sequence, mimic_qpu=False)

Validates a sequence prior to submission.
