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.

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;
