Surpassing the repeaterless bound with a photon-number encoded measurement-device-independent quantum key distribution protocol
Ozlem Erkilic, Lorcan Conlon, Biveen Shajilal +5
Decoherence is detrimental to quantum key distribution (QKD) over large distances. One of the proposed solutions is to use quantum repeaters, which divide the total distance betwee…

Information back-flow in quantum non-Markovian dynamics and its connection to teleportation
Spyros Tserkis, Kade Head-Marsden, Prineha Narang
A quantum process is called non-Markovian when memory effects take place during its evolution. Quantum non-Markovianity is a phenomenon typically associated with the information ba…
