Time-delayed quantum feedback using a lattice of dissipative oscillators

ORAL

Abstract

Time-delayed quantum feedback has been a commonly used controlling method in quantum systems. However, solutions to these systems have been difficult to obtain due to their non-Markovian nature. Here, we show that time-delayed quantum feedback can be introduced with a novel setup, which is composed of a lattice of dissipative oscillators. This approach provides a novel viewpoint of time-delayed quantum dynamics and gives us accessibility to unexplored regimes. Further, with more tunability, it could find applications in quantum information processing.
