RydOpt - A Multiqubit Rydberg Gate Optimizer

RydOpt is a Python package for the optimization of laser pulses implementing two- and multiqubit Rydberg gates in neutral atom quantum computing platforms. The optimization methods support GPUs and multi-core CPUs, using an efficient implementation based on JAX.

Install the software with pip (requires Python ≥ 3.10; for enabling GPU support and tips, see our extended installation instructions):

pip install rydopt
