Minimizing irreversible losses in quantum systems by local counterdiabatic driving
Abstract
Losses are ubiquitous in manipulating complex systems. They arise from our lack of control on the microscopic degrees of freedom of the system. A universal way to minimize losses is to consider adiabatic processes. These processes are, however, very slow, which significantly limits their power. In this work, we show how to speed up these protocols for general complex (quantum) systems. Although dissipation cannot be avoided, we show how it can be reduced significantly with only local access to the system. Applications range from quantum information technologies to preparing experiments and even controlling complicated classical systems, such as those found in nature.
