Qobj

classmethod Qobj.from_dict(data)

Create a new QASMQobj object from a dictionary.

Parameters

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

Returns

The QasmQobj from the input dictionary.

Return type

QasmQobj

Qobj.to_dict()

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)

Returns

A dictionary representation of the QasmQobj object

Return type

dict
