ReCirq

Research using Cirq!

This project contains modules for running quantum computing applications and
experiments through Cirq. By way of example, we also document best practices
for setting up robust experimental pipelines.

Installation and Documentation

ReCirq is not available as a PyPI package. Please clone this repository and
install from source:

shellCopy
cd recirq/
pip install .

Documentation is available at https://quantumai.google/cirq/experiments.

ReCirq leverages Cirq as a quantum programming language and SDK.

Google Quantum AI has a suite of open-source software.
From high-performance simulators, to novel tools for expressing and
analyzing fault-tolerant quantum algorithms, our software stack lets you
develop quantum programs for a variety of applications.
