qBraid-QIR 0.5.0

Release 0.5.0 (December 15, 2025)

Summary

➕ New Features

• Added a QIR to squin conversion method which allows users to execute QIR programs on squin enabled backends. This feature also opens up the Squin representation to many formats such as QASM, and Cirq using the built in qbraid-qir converters. Eg. - (#252)

# Converting a PyQIR module to squin
from qbraid_qir.squin import load
from pyqir import BasicQisBuilder, SimpleModule

mod = SimpleModule("ghz", num_qubits=3, num_results=3)
qis = BasicQisBuilder(mod.builder)

qis.h(mod.qubits[0])
qis.cx(mod.qubits[0], mod.qubits[1])
qis.cx(mod.qubits[1], mod.qubits[2])

squin_kernel = load(mod._module)
squin_kernel.print()

Output:

func.func @main() -> !py.NoneType {
  ^0(%main_self):
  │ %0 = func.invoke new() : !py.Qubit maybe_pure=False
  │ %1 = func.invoke new() : !py.Qubit maybe_pure=False
  │ %2 = func.invoke h(%0) : !py.NoneType maybe_pure=False
  │ %3 = func.invoke x(%0) : !py.NoneType maybe_pure=False
  │ %4 = func.invoke x(%1) : !py.NoneType maybe_pure=False
  │ %5 = py.constant.constant 1.5707963267948966 : !py.float
  │ %6 = func.invoke rx(%5, %0) : !py.NoneType maybe_pure=False
  │ %7 = func.const.none() : !py.NoneType
  │      func.return %7
} // func.func main
