Optimal Control of Quantum Squeezed States — •Anton Halaski, Matthias G. Krauß, Daniel Basilewitsch, and Christiane P. Koch — Freie Universität Berlin, Berlin, Germany

Squeezed states are interesting for various tasks, including applications in quantum sensing or quantum information processing. We demonstrate how a mechanical resonator in an optomechanical setup can be brought into a squeezed state using optimal control theory. Using Krotov’s method [Reich et al. J. Chem. Phys. 136, 104103 (2012)], we show how optimal control theory can reduce the time needed for squeezed state generation by several orders of magnitude compared to protocols with constant driving. Further, we derive a general protocol for acquiring squeezed states, which not only allows us to simplify the general pulse shapes but also to understand the physical processes during the time evolution of the system.
