Quantum optical impurity models in interacting waveguide QED
Adrian Paul Misselwitz, Jacquelin Luneau, Peter Rabl
We consider a generic model for interacting waveguide QED systems, where photons in a coupled-cavity array localize around atomic impurities while simultaneously interacting throug…
Entangling remote qubits through a two-mode squeezed reservoir
A. Andrés-Juanes, J. Agustí, R. Sett +5
The distribution of entanglement across distant qubits is a central challenge for the operation of scalable quantum computers and large-scale quantum networks. Existing approaches…
Theory of Multi-photon Processes for Applications in Quantum Control
Longxiang Huang, Jacquelin Luneau, Johannes Schirk +5
We present a general theoretical framework for evaluating multi-photon processes in periodically driven quantum systems, which have been identified as a versatile tool for engineer…
All-mechanical coherence protection and fast control of a spin qubit
Eliza Cornell, Zhujing Xu, Zhaoyou Wang +9
In a phononic quantum network, quantum information is stored and processed within stationary nodes defined by solid-state spins, and the information is routed between nodes by phon…
Non-Markovian thermal reservoirs for autonomous entanglement distribution
Joan Agustí, Christian M. F. Schneider, Kirill G. Fedorov +2
We describe a novel scheme for the generation of stationary entanglement between two separated qubits that are driven by a purely thermal photon source. While in this scenario the…
Unraveling superradiance: Entanglement and mutual information in collective decay
Xin H. H. Zhang, Daniel Malz, Peter Rabl
We study the collective decay of an initially inverted ensemble of two-level emitters in two distinct scenarios: when coupled to a squeezed photonic reservoir and when interacting…
