Quantum Communication - Men In Black _ www.insight.spruz.com

http://www.insight.spruz.com __ Quantum communication complexity: Although entanglement on its own cannot be used for communication, it surprisingly can produce effects as if information had been transferred: entanglement can save on classical communication when the goal is to compute a function whose input data is distributed among remote parties. The minimal amount of information that has to be exchanged to accomplish the task defines its complexity. A reduction of communication complexity is important for speeding up distributed computations, for example within circuits our nurones.
