Certifying the Topology of Quantum Networks: Theory and Experiment
Lisa T. Weinbrenner, Nidhin Prasannan, Kiara Hansenne +5
Distributed quantum information in networks is paramount for global secure quantum communication. Moreover, it finds applications as a resource for relevant tasks, such as clock sy…
Continuous-variable quantum optics and resource theory for ultrafast semiconductor spectroscopy
Carolin Lüders, Franziska Barkhausen, Matthias Pukrop +4
In this review, we discuss the use of continuous variable spectroscopy techniques for investigating quantum coherence and light-matter interactions in semiconductor systems with ul…
Experimental Observation of Topological Quantum Criticality
Sonja Barkhofen, Syamsundar De, Jan Sperling +5
We report on the observation of quantum criticality forming at the transition point between topological Anderson insulator phases in a one-dimensional photonic quantum walk with sp…
Lossy SU(1,1) interferometers in the single-photon-pair regime
Matteo Santandrea, Kai-Hong Luo, Michael Stefszky +3
The success of quantum technologies is intimately connected to the possibility of using them in real-world applications. To this aim, we study the sensing capabilities of quantum S…
Entanglement-assisted quantum speedup: Beating local quantum speed limits
Farha Yasmin, Jan Sperling
Research in quantum information science aims to surpass the scaling limitations of classical information processing. From a physicist's perspective, performance improvement involve…
Tracking quantum coherence in polariton condensates with time-resolved tomography
Carolin Lüders, Matthias Pukrop, Franziska Barkhausen +6
Long-term quantum coherence constitutes one of the main challenges when engineering quantum devices. However, easily accessible means to quantify complex decoherence mechanisms are…
