Description:

pyqir 0.10.4

PyQIR
The pyqir package provides the ability to generate
QIR as well as an easy way to
parse and analyze QIR.
QIR generation is intended to be used by code automating translation processes
enabling the conversion in some format to QIR via Python; i.e., this is a
low-level API intended to be used as a bridge to existing Python frameworks
enabling the generation of QIR rather than directly consumed by an end-user. It
is not intended to be used as a framework for algorithm and application
development.
Installation
The package is released on PyPI and can be installed via pip:
pip install pyqir

Examples
PyQIR examples can be found in this repository's examples folder.
Generation
The following code creates QIR for a Bell pair before measuring each qubit and
returning the result. The unoptimized QIR is displayed in the terminal when
executed:
from pyqir import BasicQisBuilder, SimpleModule

module = SimpleModule("Bell", num_qubits=2, num_results=2)
qis = BasicQisBuilder(module.builder)

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

qis.mz(module.qubits[0], module.results[0])
qis.mz(module.qubits[1], module.results[1])

print(module.ir())

The QIR output will look like:
; ModuleID = 'Bell'
source_filename = "Bell"

%Qubit = type opaque
%Result = type opaque

define void @main() #0 {
entry:
call void @__quantum__qis__h__body(%Qubit* null)
call void @__quantum__qis__cnot__body(%Qubit* null, %Qubit* inttoptr (i64 1 to %Qubit*))
call void @__quantum__qis__mz__body(%Qubit* null, %Result* null)
call void @__quantum__qis__mz__body(%Qubit* inttoptr (i64 1 to %Qubit*), %Result* inttoptr (i64 1 to %Result*))
ret void
}
