OpenQASM

Specs, examples and tools for the OpenQASM intermediate representation.

Current version

The latest version is: 2.0.

About this project

On this repository you'll find all the documentation related to the OpenQASM in PDF, including the sources to generate it. Also some useful OpenQASM examples.

Language specs

The language documentation is available under the spec folder in LaTex language. Here we provide a human-readable version of it in PDF format.

Examples

The examples can be found under the [examples] folder.

They are OpenQASM files, i.e.:

// Repetition code syndrome measurement
OPENQASM 2.0;
include "qelib1.inc";
qreg q[3];
qreg a[2];
creg c[3];
creg syn[2];
gate syndrome d1,d2,d3,a1,a2
{
  cx d1,a1; cx d2,a1;
  cx d2,a2; cx d3,a2;
}
x q[0]; // error
barrier q;
syndrome q[0],q[1],q[2],a[0],a[1];
measure a -> syn;
if(syn==1) x q[0];
if(syn==2) x q[2];
if(syn==3) x q[1];
measure q -> c;

Tests

The official OpenQASM official conformance test suite is included in this repo.
