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(
qir_bitcode=qir_in,
comp_pass=FullPeepholeOptimise(allow_swaps=False),
target_1q_gates={OpType.Rx, OpType.Rz},
target_2q_gates={OpType.ZZPhase},
)
Both the input and the output are Python bytes
objects.
Provided the pass preserves the circuit semantics, apply_qirpass
preserves
the QIR semantics.
