pyquil

PyQuil is a Python library for quantum programming using Quil, the quantum instruction language developed at Rigetti Computing. PyQuil serves three main functions:

• Easily generating Quil programs from quantum gates and classical operations
• Compiling and simulating Quil programs using the Quil Compiler (quilc) and the Quantum Virtual Machine (QVM)
• Executing Quil programs on real quantum processors (QPUs) using [Quantum Cloud Services][qcs-paper] (QCS)

PyQuil has a ton of other features, which you can learn more about in the docs.
