ParaQeet - A quantum optimal control toolkit with simple parameter management¶
You can find quick information on installation and contributing in the README and CONTRIBUTING documents.
Choose a pulse parametrisation, simulate a quantum system, and optimise.
Combining Quantum Optimal Control methods with automatic differentiation with JAX. Aimed at resource efficient computation.
We use a top-down approach to make the codebase modular. Each module interacts only with the module above it in hierarchy.
Currently implementated optimization methods - GRAPE: Gradient Ascent Pulse Enginnering - GOAT: Gradient Optimization of Analytic conTrols - dCRAB : (Gradient based) dressed Chopped RAndom Basis
