Cirq

Cirq is a Python library designed for the creation, manipulation, and execution of quantum circuits on quantum computers and simulators. It supports the development of circuits with flexible gate definitions and parameterization, alongside features such as circuit transformation and noise modeling, making it well-suited for applications in noisy intermediate-scale quantum (NISQ) computing. Notable integrations with tools like NumPy, SciPy, and qsim, along with cross-platform compatibility, enhance its usability for researchers and developers in the quantum computing field.
