Quantum sampling in hybrid light-matter systems with mixed statistics
Franziska Barkhausen, Laura Ares, Stefan Schumacher +1
Boson sampling is one of the most prominent methods to verify quantum advantage, harnessing the computational complexity of the permanent of a network matrix. Similar quantum sampl…
Entanglement between dependent degrees of freedom: Quasiparticle correlations
Franziska Barkhausen, Laura Ares Santos, Stefan Schumacher +1
Common notions of entanglement are based on well-separated subsystems. However, obtaining such independent degrees of freedom is not always possible because of physical constraints…
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…
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…
Structuring co- and counter-flowing currents of polariton condensates in concentric ring-shaped potentials
Franziska Barkhausen, Matthias Pukrop, Stefan Schumacher +1
We investigate the current flow of microcavity polariton condensates loaded into concentric ring-shaped potentials. The tunneling of the condensates between different potential rin…
Multistable circular currents of polariton condensates trapped in ring potentials
Franziska Barkhausen, Stefan Schumacher, Xuekai Ma
We demonstrate the formation and trapping of different stationary solutions, oscillatory solutions, and rotating solutions of a polariton condensate in a planar semiconductor micro…
