Multichannel read-out for arrays of metallic magnetic calorimeters

F. Mantegazzini, S. Allgeier, A. Barth +12

Metallic magnetic micro-calorimeters (MMCs) operated at millikelvin temperature offer the possibility to achieve eV-scale energy resolution with high stopping power for X-rays and…

Phonon-induced enhancement of photon entanglement in quantum dot-cavity systems

Tim Seidelmann, Florian Ungar, Andreas M. Barth +4

We report on simulations of the degree of polarization entanglement of photon pairs simultaneously emitted from a quantum dot-cavity system that demand revisiting the role of phono…

From strong to weak temperature dependence of the two-photon entanglement resulting from the biexciton cascade inside a cavity

Tim Seidelmann, Florian Ungar, Moritz Cygorek +4

We investigate the degree of entanglement quantified by the concurrence of photon pairs that are simultaneously emitted in the biexciton-exciton cascade from a quantum dot in a cav…

Path-integral approach for nonequilibrium multi-time correlation functions of open quantum systems coupled to Markovian and non-Markovian environments

Michael Cosacchi, Moritz Cygorek, Florian Ungar +3

Using a real-time path integral approach we develop an algorithm to calculate multi-time correlation functions of open few-level quantum systems that is applicable to highly nonequ…

Comparison of different concurrences characterizing photon-pairs generated in the biexciton cascade in quantum dots coupled to microcavities

Moritz Cygorek, Florian Ungar, Tim Seidelmann +4

We compare three different notions of concurrence to measure the polarization entanglement of two-photon states generated by the biexciton cascade in a quantum dot embedded in a mi…

Nonlinear cavity feeding and unconventional photon statistics in solid-state cavity QED revealed by many-level real-time path-integral calculations

Moritz Cygorek, Andreas M. Barth, Florian Ungar +2

The generation of photons in a microcavity coupled to a laser-driven quantum dot interacting with longitudinal acoustic (LA) phonons is studied in the regime of simultaneously stro…
