Pulse shaping could hold the key to secure quantum networks

Abstract:
Two researchers from Nanjing University looked at the behavior of a particular type of link where information is first encoded on a quantum dot, a small lump of material that acts like a single atom. This quantum dot sits between two mirrors, so when it radiates its information, the photon is "caught" by the mirrors and deposited into a fiber optic cable. The fiber optic cable transmits the photon to a second quantum dot that also happens to be sitting between two mirrors. In this case, the mirrors "catch" the photon and bounce it off the quantum dot until it finally absorbs it. At this point, information transfer has occurred.
