Description:

qbraidqir 0.2.2

qBraid-SDK extension providing support for QIR conversions.

Motivation

This project aims to make QIR representations accessible via the qBraid-SDK transpiler, and by doing so, open the door to language-specific conversions from any and all high-level quantum languages supported by qbraid. See QIR Alliance: why do we need it?.
Installation
qBraid-QIR requires Python 3.9 or greater, and can be installed with pip as follows:
pip install qbraid-qir

Optional dependencies
qBraid-QIR offers integrations that require extra (optional) dependencies, which can be installed as follows:
For Cirq to QIR conversions, install the cirq extra:
pip install 'qbraid-qir[cirq]'

For OpenQASM 3 to QIR conversions, install the qasm3 extra:
pip install 'qbraid-qir[qasm3]'

Install from source
You can also install from source by cloning this repository and running a pip install command
in the root directory of the repository:
git clone https://github.com/qBraid/qbraid-qir.git
cd qbraid-qir
pip install .

To include optional dependencies when installing from source, use the same "extras_require" format, e.g.
pip install '.[cirq,qasm3]'

Check version
You can view the version of qbraid-qir you have installed within a Python shell as follows:
In [1]: import qbraid_qir

In [2]: qbraid_qir.__version__

Usage examples
Cirq conversions
import cirq
from qbraid_qir.cirq import cirq_to_qir

q0, q1 = cirq.LineQubit.range(2)

circuit = cirq.Circuit(
cirq.H(q0),
cirq.CNOT(q0, q1),
cirq.measure(q0, q1)
)

module = cirq_to_qir(circuit, name="my-circuit")

ir = str(module)

OpenQASM 3 conversions
from qbraid_qir.qasm3 import qasm3_to_qir

program = """
OPENQASM 3;
include "stdgates.inc";

qubit[2] q;
bit[2] c;

h q[0];
cx q[0], q[1];

measure q[0] -> c[0];
measure q[1] -> c[1];
"""

module = qasm3_to_qir(program, name="my-program")

ir = str(module)

Add QIR node to qBraid conversion graph
from qbraid_qir.cirq import cirq_to_qir
from qbraid.transpiler import Conversion, ConversionGraph

graph = ConversionGraph()

conversion = Conversion("cirq", "qir", cirq_to_qir)

graph.add_conversion(conversion)

graph.plot()
