SUMMARY:Quantum relay using semiconductor light sources (SP Workshop) - Mr
  Ziheng Xiang (University of Cambridge\, Semiconductor Physics Group)
DTSTART:20161102T141500Z

UID:TALK68972@talks.cam.ac.uk
CONTACT:Teri Bartlett
DESCRIPTION:The no cloning theorem guarantees the security in the quantum 
 communication\, making it valuable in terms of information safety. This ta
 lk will focus on the general idea of quantum communication based on the pr
 evious work done at Toshiba Research Europe Limited including the quantum 
 information carrier\, quantum cryptography (QKD)\, entangled photon pair g
 eneration and quantum teleportation (quantum relay). The principle of enta
 nglement and the generation of entangled photon pairs on the using exciton
  and biexciton cascade in semiconductor quantum dots will be explained. Th
 e BB84 protocol of QKD will be shown for illustrating the quantum cryptogr
 aphy. The quantum relay and the current 1km prototype based on the quantum
  teleportation will finally be introduced and explained.
LOCATION:Mott Seminar Room (Mott Building Room 531)\, Cavendish Laboratory
