qiskit.qobj.QasmQobj

class QasmQobj(qobj_id=None, config=None, experiments=None, header=None)

A QASM Qobj.

Instatiate a new QASM Qobj Object.

Each QASM Qobj object is used to represent a single payload that will be passed to a Qiskit provider. It mirrors the Qobj the published Qobj specification for OpenQASM experiments.

매개변수

• qobj_id (str) – An identifier for the qobj

• config (QasmQobjRunConfig) – A config for the entire run

• header (QobjHeader) – A header for the entire run

• experiments (list) – A list of lists of QasmQobjExperiment objects representing an experiment

__init__(qobj_id=None, config=None, experiments=None, header=None)

매개변수

Methods

__init__([qobj_id, config, experiments, header])	Instatiate a new QASM Qobj Object.
from_dict(data)	Create a new QASMQobj object from a dictionary.
to_dict([validate])	Return a dictionary format representation of the QASM Qobj.

classmethod from_dict(data)

Create a new QASMQobj object from a dictionary.

매개변수

data (dict) – A dictionary representing the QasmQobj to create. It will be in the same format as output by to_dict().

반환값

The QasmQobj from the input dictionary.

QasmQobj

to_dict(validate=False)

Return a dictionary format representation of the QASM Qobj.

Note this dict is not in the json wire format expected by IBMQ and qobj specification because complex numbers are still of type complex. Also this may contain native numpy arrays. When serializing this output for use with IBMQ you can leverage a json encoder that converts these as expected. For example:

import json
import numpy

class QobjEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, numpy.ndarray):
            return obj.tolist()
        if isinstance(obj, complex):
            return (obj.real, obj.imag)
        return json.JSONEncoder.default(self, obj)

json.dumps(qobj.to_dict(), cls=QobjEncoder)

매개변수

validate (bool) – When set to true validate the output dictionary against the jsonschema for qobj spec.
