Journal Club for Quantum Physics and Machine Learning

Schedule

 

Next Journal Club Meeting: Tuesday, 21st November 2021, 5:30pm CET.

Jonathon Brown (Queen's University Belfast) will present the following paper: Reinforcement learning-enhanced protocols for coherent population-transfer in three-level quantum systems

Abstract: We deploy a combination of reinforcement learning-based approaches and more traditional optimization techniques to identify optimal protocols for population transfer in a multi-level system. We constraint our strategy to the case of fixed coupling rates but time-varying detunings, a situation that would simplify considerably the implementation of population transfer in relevant experimental platforms, such as semiconducting and superconducting ones. Our approach is able to explore the space of possible control protocols to reveal the existence of efficient protocols that, remarkably, differ from (and can be superior to) standard Raman, STIRAP or other adiabatic schemes. The new protocols that we identify are robust against both energy losses and dephasing.
