Efficient entanglement distillation without quantum memory

Abdelkhalek, Daniela; Syllwasschy, Mareike; Cerf, Nicolas J.; Fiurasek, Jaromir; Schnabel, Roman (London : Nature Publishing Group, 2016)

Entanglement distribution between distant parties is an essential component to most quantum communication protocols. Unfortunately, decoherence effects such as phase noise in optical fibres are known to demolish entanglement. ...
Implementation of continuous-variable quantum key distribution with composable and one-sided-device-independent security against coherent attacks

Gehring, Tobias; Handchen, Vitus; Duhme, Jörg; Furrer, Fabian; Franz, Torsten; Pacher, Christoph; Werner, Reinhard F.; Schnabel, Roman (London : Macmillan Publishers Limited, 2015)

Secret communication over public channels is one of the central pillars of a modern information society. Using quantum key distribution this is achieved without relying on the hardness of mathematical problems, which might ...
Population difference gratings created on vibrational transitions by nonoverlapping subcycle THz pulses

Arkhipov, Rostislav; Pakhomov, Anton; Arkhipov, Mikhail; Babushkin, Ihar; Demircan, Ayhan; Morgner, Uwe; Rosanov, Nikolay (London : Nature Publishing Group, 2021)

We study theoretically a possibility of creation and ultrafast control (erasing, spatial frequency multiplication) of population density gratings in a multi-level resonant medium having a resonance transition frequency in ...
