qadence-protocols 0.1.3

Protocols interface for running experiments using Qadence.

Qadence-Protocols

Qadence-Protocols is a Python package that provides extra functionality for Qadence.

Feature highlights

• A block-based system for composing complex digital-analog programs in a flexible and scalable manner, inspired by the Julia quantum SDK Yao.jl and functional programming concepts.

• A simple interface to work with interacting neutral-atom qubit systems using arbitrary registers topologies.

• An intuitive expression-based system developed on top of the symbolic library Sympy to construct parametric quantum programs easily.

• High-order generalized parameter shift rules for differentiating parametrized quantum operations.

• Out-of-the-box automatic differentiability of quantum programs with PyTorch integration.

• Efficient execution on a variety of different purpose backends: from state vector simulators to tensor network emulators and real devices.

Installation guide

Qadence-Protocols will soon be available on PyPI.

pip install qadence_protocols

Setting up qadence in development mode

We recommend to use the hatch environment manager to install qadence_protocols from source:

python -m pip install hatch

# get into a shell with all the dependencies
python -m hatch shell

# run a command within the virtual environment with all the dependencies
python -m hatch run python my_script.py

WARNING hatch will not combine nicely with other environment managers such as Conda. If you still want to use Conda, install it from source using pip:

# within the Conda environment
python -m pip install -e .
