Boosting energy-time entanglement using coherent time-delayed feedback

چکیده
The visibility of the two-photon interference in Franson interferometer serves as a measure energy-time entanglement photons. We propose to control second-order coherence function by implementing coherent time-delayed feedback mechanism. Simulating non-Markovian dynamics within matrix product state framework, we find that for two photons emitted from three-level system (3LS) ladder configuration can be enhanced significantly wide range parameters slowing down decay upper level 3LS.

Control of Time-delayed Lpv Systems Using Delayed Feedback
In this paper, the delayed (memory) feedback synthesis problem for linear parameter varying (LPV) systems with parameter-varying time delays is introduced and addressed. It is assumed that the state-space data and the timedelay depend continuously on the parameters which are measurable in real-time and vary in a compact set with bounded variation rates. Synthesis conditions for stabilization an...
متن کاملTime-delayed Feedback Control of the Energy Resource Chaotic System
In this paper, the control of energy resource chaotic system is investigated by timedelayed feedback control (TDFC) method. The controllability and the stability of the equilibriums of the system are verified. Several stabile periodic orbits are got in the numerical simulations, which shows the effectively of TDFC method.
متن کاملTime-delayed feedback in neurosystems.
The influence of time delay in systems of two coupled excitable neurons is studied in the framework of the FitzHugh-Nagumo model. A time delay can occur in the coupling between neurons or in a self-feedback loop. The stochastic synchronization of instantaneously coupled neurons under the influence of white noise can be deliberately controlled by local time-delayed feedback. By appropriate choic...
متن کاملTime-Delayed Quantum Feedback Control.
A theory of time-delayed coherent quantum feedback is developed. More specifically, we consider a quantum system coupled to a bosonic reservoir creating a unidirectional feedback loop. It is shown that the dynamics can be mapped onto a fictitious series of cascaded quantum systems, where the system is driven by past versions of itself. The derivation of this model relies on a tensor network rep...
متن کاملPostselection-free energy-time entanglement.
We report a two-photon interference experiment that realizes a postselection-free test of Bell’s inequality based on energy-time entanglement. In contrast with all previous experiments of this type, the employed entangled states are obtained without the use of a beam splitter or a short coincidence window to ‘‘throw away’’ unwanted amplitudes. A ~95.061.4!% interference fringe visibility is obs...
