  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.
