Quantum Limits of Optical Communication
24-26 February 2016, Warsaw, Poland


Standard optical communication systems operate with efficiencies lower that limits defined by quantum physics. In recent years, significant progress has been made in identifying ultimate capacities of optical channels, developing and implementing sub-shot noise receivers, and understanding non-classical effects such as superadditivity of accessible information through collective readout. The purpose of this workshop is to review these advances and to identify further steps towards practical exploitation of quantum enhancement in optical communication.

Main topics include:

  • Sub-shot noise receivers
  • Collective detection
  • Ultimate capacity of optical channels
  • Quantum-limited optical signal discrimination
  • Mode multiplexing and demultiplexing
  • Noise in optical communication links
