pairinteraction GUI

  • PairInteraction software: Simulates systems of one or two Rydberg atoms, taking into account electric and magnetic fields in arbitrary directions as well as multipole interaction. Supports divalent atoms via multi-channel quantum defect theory. The software consists of a high-performance C++ backend, a Python library as a convenient API, and an easy-to-use graphical user interface for pair potential calculations.
  • RydOpt Python package: Optimizes 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.
