Hyperloss from coherent spatial-mode mixing in quantum-correlated networks
Stephan Grebien, Julian Gurs, Roman Schnabel +1
Quantum-correlated networks distribute quantum resources such as squeezed and entangled states. These states are central to modern quantum technology, including photonic quantum co…

Extended analysis of distillation and purification of squeezed states of light
JaromÃr Fiurášek, Stephan Grebien, Roman Schnabel
Squeezed states of light are one of the most important fundamental resources for quantum optics, optical quantum information processing and quantum sensing. Recently, it has been e…

Tomographic measurement data of states that never existed
Julian Göttsch, Stephan Grebien, Felix Pein +6
Microscopic Schr{ö}dinger cat states are generated from quantum correlated fields using a probabilistic heralding photon subtraction event. Subsequent quantum state tomography pro…
