Open Quantum Assembly Language

TL;DR

OpenQASM is a standardized quantum assembly language enabling the implementation and execution of low-depth quantum circuits with features like measurement, reset, and feedback, compatible with IBM Q Experience.

Contribution

This paper introduces OpenQASM, a universal, human-readable quantum assembly language supporting complex quantum operations and integration with existing quantum hardware and tools.

Findings

OpenQASM supports universal quantum circuits over CNOT and SU(2) bases.

It includes features like measurement, reset, and fast feedback.

OpenQASM can be used with IBM Q Experience for experimental quantum computing.

Abstract

This document describes a quantum assembly language (QASM) called OpenQASM that is used to implement experiments with low depth quantum circuits. OpenQASM represents universal physical circuits over the CNOT plus SU(2) basis with straight-line code that includes measurement, reset, fast feedback, and gate subroutines. The simple text language can be written by hand or by higher level tools and may be executed on the IBM Q Experience.
