Unraveling Mirror Properties in Time-Delayed Quantum Feedback Scenarios
Fabian M. Faulstich, Manuel Kraft, Alexander Carmele
We derive in the Heisenberg picture a widely used phenomenological coupling element to treat feedback effects in quantum optical platforms. Our derivation is based on a microscopic…

Time-delayed quantum coherent Pyragas feedback control of photon squeezing in a degenerate parametric oscillator
Manuel Kraft, Sven Moritz Hein, Judith Lehnert +3
Quantum coherent feedback control is a measurement-free control method fully preserving quantum coherence. In this paper we show how time-delayed quantum coherent feedback can be u…
