| Abstract: | We present an efficient entanglement concentration protocol(ECP)for mobile electrons with charge detection.This protocol is quite different from other ECPs for one can obtain a maximally entangled pair from a pair of less-entangled state and a single mobile electron with a certain probability.With the help of charge detection,it can be repeated to reach a higher success probability.It also does not need to know the coefficient of the original less-entangled states.All these advantages may make this protocol useful in current distributed quantum information processing. |
