A digital twin of atomic ensemble quantum memories
Elizabeth Robertson, Benjamin Maaß, Konrad Tschernig +1
Accurate performance estimation of experimentally demonstrated quantum memories is key to understand the nuances in their deployment in photonic quantum networks. While several sof…
Two-photon edge states in photonic topological insulators: topological protection versus degree of entanglement
Konrad Tschernig, Alvaro Jimenez-Galan, Demetrios N. Christodoulides +4
Topological insulators combine insulating properties in the bulk with scattering-free transport along edges, supporting dissipationless unidirectional energy and information flow e…
Direct observation of the particle exchange phase of photons
Konrad Tschernig, Chris Müller, Malte Smoor +5
Quantum theory stipulates that if two particles are identical in all physical aspects, the allowed states of the system are either symmetric or antisymmetric with respect to permut…
Exceptional points of any order in a single, lossy, waveguide beamsplitter by photon-number-resolved detection
Mario A. Quiroz-Juárez, Armando Perez-Leija, Konrad Tschernig +5
Exceptional points (EPs) are degeneracies of non-Hermitian operators where, in addition to the eigenvalues, corresponding eigenmodes become degenerate. Classical and quantum photon…
