QPUBackend

class pulser.backend.QPUBackend(sequence, connection)

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.

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.

Return type:

_OpenBatchContextManager

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 parameters for each job to execute. Each mapping must contain a defined ‘runs’ field specifying the number of times to run the same sequence. If the sequence is parametrized, the values for all the variables necessary to build the sequence must be given in it’s own mapping, for each job, under the ‘variables’ field.

• 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.

Return type:

None

static validate_sequence(sequence, mimic_qpu=False)

Validates a sequence prior to submission.

Return type:

None
