Module for optimizing QIR using pytket.

Project description


This module provides a method to optimize QIR using pytket.


Python 3.10, 3.11 or 3.12 is required.

To install from PyPI:

pip install pytket-qirpass


This module provides a single function, apply_qirpass, which takes as input

  • some QIR bitcode
  • a pytket compilation pass
  • a target gateset

and outputs some new QIR bitcode, where the pass has been applied to the basic blocks in the input program, followed by a rebase to the target gateset.

For example:

from pytket_qirpass import apply_qirpass
from pytket.circuit import OpType
from pytket.passes import FullPeepholeOptimise

qir_out = apply_qirpass(
    target_1q_gates={OpType.Rx, OpType.Rz},

Both the input and the output are Python bytes objects.

Provided the pass preserves the circuit semantics, apply_qirpass preserves the QIR semantics.
