SUMMARY:Quantum Reading of Digital Memories - Stefano Pirandola (Universit
 y of York)
DTSTART:20111201T141500Z

CONTACT:Paul Skrzypczyk
DESCRIPTION:Optical memories such as CDs and DVDs are central devices in o
 ur communication system. However\, further progress in optical storage str
 ictly relies on advances in Optics and Materials science. As an example\, 
 dye-based optical discs cannot be read by UV laser light\, because of the 
 inevitable degradation of their organic layers. This clearly puts a physic
 al limit to their maximum storage capacity.\n\nIn this talk I will discuss
  a new approach to the readout of optical memories which is based on the u
 se of quantum light. Thanks to its properties\, this kind of light can ret
 rieve digital information by using extremely low energy. I will discuss ho
 w such a feature can have non-trivial implications in terms of increasing 
 storage capacities and data-transfer rates.
