OpenQASM 2.0 --> OpenQASM 3.0 conversion function

[ryanhill1]

Write a function in qbraid.interface.qbraid_qasm.tools.py that converts an OpenQASM 2.0 program / string to an OpenQASM 3.0 program / string.

Resources:

• https://openqasm.com/
• https://github.com/openqasm/openqasm
• https://github.com/openqasm/openqasm/tree/OpenQASM2.x

Example usage:

>>> print(qasm_str)
OPENQASM 2.0;
include "qelib1.inc";
qreg q[2];
creg c[2];
h q[0];
cx q[0],q[1];
measure q[0] -> c[0];
measure q[1] -> c[1];
>>> print(convert_to_qasm3(qasm_str))
OPENQASM 3.0;
bit[2] b;
qubit[2] q;
h q[0];
cnot q[0], q[1];
b[0] = measure q[0];
b[1] = measure q[1];

One rough example of a way you could test for coverage:

from qbraid import circuit_wrapper
from qbraid.interface import random_circuit
from qbraid.interface.qbraid_qasm.tools import convert_to_qasm3

from braket.circuits.serialization import IRType

for _ in range(100):
    circuit = random_circuit("braket")
    qasm2_str = circuit_wrapper(circuit).transpile("qasm")
    qasm3_test = convert_to_qasm3(qasm2_str)
    qasm3_expected = circuit.to_ir(IRType.OPENQASM).source
    assert qasm3_test.strip() == qasm3_expected.strip()
