Abstract: In this talk, we consider the following communication task. Alice and Bob each are given a set of input variables of n-bit bit strings. They want to exchange input information without classical communication. By exploiting a photon’s coherent superposition for “two-way signaling” in Mark-Zehnder interferometers, the total information gain can be as large as n+1 bits. This result indicates that the “depth/level” of local operations with signaling resource can be equivalent to the amount of classical communication with non-signaling resource.
