Researchers Propose PEPRino Algorithm for High-Fidelity Multi-Qubit Control Protocols

Quantum ZeitgeistAugust 19, 20265 min read

Pulse engineering via projection of response functions at infinite nonlinear order Achieving faster convergence in both iteration steps and computational time represents a step forward in quantum control. This new algorithm, PEPRino, surpasses the Chopped Random Basis method in a two-qubit system, offering a hyperparameter-free optimisation strategy. By leveraging response theory, it efficiently generates high-fidelity control protocols for multi-qubit systems.

Scientists are increasingly encountering optimisation problems in a wide range of scientific disciplines, but the corresponding optimisation algorithms often display a strong dependence on hyperparameters that significantly influence performance and convergence. For the optimal implementation of quantum algorithms, these challenges are further amplified by high-dimensional control landscapes and the need for high-fidelity operations. A 34% reduction in computational time for optimising quantum controls was achieved by researchers at Zentrum f¨ur Optische Quantentechnologien, in collaboration with Institut f¨ur Quantenphysik and The Hamburg Centre for Ultrafast Imaging. This surpasses the performance of existing Chopped Random Basis methods.…
