Eavesdropper localization for quantum and classical channels via nonlinear scattering
Alexandra Popp, Florian Sedlmeir, Birgit Stiller +1
Optical fiber networks are part of important critical infrastructure and known to be prone to eavesdropping attacks. Hence cryptographic methods have to be used to protect communic…
Squeezed vacuum states from a whispering gallery mode resonator
Alexander Otterpohl, Florian Sedlmeir, Ulrich Vogl +9
Squeezed vacuum states enable optical measurements below the quantum limit and hence are a valuable resource for applications in quantum metrology and also quantum communication. H…
The Standard Quantum Limit of Coherent Beam Combining
C. R. Muller, F. Sedlmeir, V. O. Martynov +2
Coherent beam combining refers to the process of generating a bright output beam by merging independent input beams with locked relative phases. We report the first quantum mechani…
