Interaction-free measurements based communication scheme for long-haul data transfer

Abstract

A communication scheme based on interaction-free measurements is proposed here, that is applicable for long-haul communications. It is shown that the scheme allows the transmitter to transfer real information at the receiver end in a finite amount of time, which is independent of their distance of separation. Now, as the distance of separation increases, effective speed of information transfer increases due to the constant receive-after-time delay. Hence, this communication technique is faster than the conventional way of information transfer at a speed of light, for communications over long distances.
