Directional Coupling for Quantum Computing and Communication

Abstract

We introduce the concept of directional coupling, i.e., the selective transfer of a state between adjacent quantum wires, in the context of quantum computing and short-distance communication. Our analysis rests upon a mathematical analogy between a dual-channel directional coupler and a composite spin system.
