qisjob

NOTE: This project is now archived

Qisjob is rooted in early Qiskit. It does not work with Qiskit 1.0 and beyond, and its architecture does lend itself to enhancement in order to support modern Qiskit.

Qiskit Job Control

The qisjob module

The module is qisjob. It was formerly named qis_job. I'm not sure why, but I have now changed it to qisjob.

If you previously installed the module as qis_job you can uninstall that older version either by

  • pip3 uninstall qis_job
  • make uninstall_oldname

The qisjob command

The qisjob command loads and executes Qiskit experiments on simulators or on genuine quantum computing hardware such as that found at IBM Q Experience. Input is from one or more OpenQASM 2 (by default) or OpenQASM 3 (with the --qasm3_in option) source files or Qiskit QuantumCircuit Python code (with the --qc option) or from source provided via standard input in the absence of file arguments.

The command also provides some utility functions such as:

  • enumerating backend platforms
  • configuration both current and historical of backend platforms
  • status of backend platforms
  • status and results of jobs both current and historical

and other useful operations for Qiskit experimentation.

qisjob comes with NO GUARANTEE and NO WARRANTY including as regards correctness nor applicability. See LICENSE.

qisjob can run Qiskit experiments expressed as either:

  • OPENQASM Open Quantum Assembly Language
  • Qiskit Terra QuantumCircuit Python code snippet.
    • To use a code snippet, only import that which is absolutely needed in the snippet and provide no execution code.
    • Pass the name of your QuantumCircuit to the --qc argument of qisjob.py
      • If you have multiple files of this sort, all must have the same name for their QuantumCircuit object.
      • An example circuit (very long execution!) is found in the qc_examples subdirectory of the project.

You can load and run multiple files, but you cannot mix Qasm and QuantumCircuit files in the same execution of the qisjob.

QisJob is compatible with the experimental NuQasm2 project, that you can use to compile and run your OPENQASM2.0 source code. Given that you have NuQasm2 installed, you can use qisjob's -n include-path:include-path:... switch

The QisJob class

The qisjob script works by instancing an object of the class qisjob.QisJob.

You can use an object instance of the class qisjob.QisJob in your own program for its utility functions or the execute experiments on real quantum hardware and/or simulators either using OpenQASM source or Qiskit QuantumCircuit source code.

QisJob Documentation

The qisjob.QisJob object that underlies the qisjob script that can be used in your own programs has many args/kwargs.

The documentation for qisjob.QisJob is installed with the module in the site library's share/doc.

You can also read the QisJob Documentation Online

Prerequisites

Install

Do one of the following in the source directory (preferably in a Python virtual environment set up for Qiskit)

  • make # gnu make, we have provided a Makefile
  • ./setup.py install
  • pip3 install .

Note that the module name has recently (2021-02-16) changed from qis_job to qisjob. If you previously installed the module as qis_job you can uninstall that older version either by

  • pip3 uninstall qis_job
  • make uninstall_oldname

Uninstall

Do one of the following in the source directory

  • make uninstall
  • pip3 uninstall qisjob

The qisjob script has helpful help.

Qisjob loads from one or more OpenQASM source files or from a file containing a Qiskit QuantumCircuit definition in Python and runs as
experiments with reporting in CSV form. Can graph results as histogram or state-city plot. Also can give info on backend properties, qiskit
version, show circuit transpilation, etc. Can run as multiple jobs or all as one job. Exits 0 on success, 1 on argument error, 100 on runtime
error, 200 on QiskitError. Copyright 2019, 2023 Jack Woehr jwoehr@softwoehr.com PO Box 82, Beulah, Colorado 81023. Apache License, Version 2.0
