Qobj

class qiskit.qobj.Qobj(qobj_id=None, config=None, experiments=None, header=None)

ベースクラス: QasmQobj

A backwards compat alias for QasmQobj.

Initialize a Qobj object.

バージョン 0.19.0 で非推奨: The class qiskit.qobj.Qobj is deprecated as of qiskit-terra 0.19.0. It will be removed no earlier than 3 months after the release date. Instead, use QasmQobj or PulseQobj

Methods

classmethod from_dict(data)

Create a new QASMQobj object from a dictionary.

パラメータ:

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

戻り値:

The QasmQobj from the input dictionary.

戻り値の型:

QasmQobj

to_dict()

Return a dictionary format representation of the OpenQASM 2 Qobj.

Note this dict is not in the json wire format expected by IBM 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 IBM systems, 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)

戻り値:

A dictionary representation of the QasmQobj object

戻り値の型:
