Guppy is a quantum programming language that is fully embedded into Python. It allows you to write high-level hybrid quantum programs with classical control flow and mid-circuit measurements using Pythonic syntax:
from guppylang import guppy
from guppylang.std.builtins import owned
from guppylang.std.quantum import cx, h, measure, qubit, x, z
@guppy
def teleport(src: qubit @ owned, tgt: qubit) -> None:
"""Teleports the state in `src` to `tgt`."""
# Create ancilla and entangle it with src and tgt
tmp = qubit()
h(tmp)
cx(tmp, tgt)
cx(src, tmp)
# Apply classical corrections
h(src)
if measure(src):
z(tgt)
if measure(tmp):
x(tgt)
guppy.compile_module()More examples and tutorials are available here.
Guppy can be installed via pip. Requires Python >= 3.10.
pip install guppylangSee the Getting Started guide and the other examples.
