QASM conversions
Example Usage
Convert an OpenQASM 3
program to QIR
code:
from qbraid_qir import dumps
from qbraid_qir.qasm3 import qasm3_to_qir
# create a test program
program = """
OPENQASM 3;
include "stdgates.inc";
qubit[2] q;
h q[0];
cx q[0], q[1];
measure q[0] -> c[0];
measure q[1] -> c[1];
"""
# convert to QIR
module = qasm3_to_qir(program, name="bell")
# saves to .ll and .bc files in working directory
dumps(module)
print(module)
; ModuleID = 'bell'
source_filename = "bell"

Execute the QIR program using the qir-runner command line tool:
$ qir-runner -f bell.bc
