pyQuil and Quil starter package

SoftwareQuantum SDKLicence: Apache-2.0Version: 4.22.08.0 KB

pyQuil, the Python library for Rigetti's Quil instruction set: a tested example that generates a Bell program as Quil, and a guide to running it with the local QVM.

What is pyQuil?

pyQuil is the Python library for writing programs in Quil, Rigetti's quantum instruction set. Quil is a low-level language that defines classical and quantum operations in the same program.

When to use it

When you want to work on Rigetti's superconducting processors.
When you want to see a quantum program at the instruction level, very close to the hardware.

The example in this package

quil_programi.py builds the Bell program and prints its Quil text. Since compiling and running the program needs two separate servers, the example only builds the program.

Running the program

Start Rigetti's quilc (compiler) and qvm (simulator) servers with Docker:

docker run --rm -it -p 5555:5555 rigetti/quilc -R
docker run --rm -it -p 5000:5000 rigetti/qvm -S

Then in Python:

from pyquil import get_qc
qc = get_qc("2q-qvm")
result = qc.run(qc.compile(p))
print(result.get_register_map()["ro"])

Installation and running

pip install pyquil
python quil_programi.py

Tested with: pyquil 4.22.0, Python 3.12.
