18.1 Introduction
Much of the theory as well as experiments on quantum information science have originally been developed in the realm of discrete variables (quantum bits) since a lot of intuition of classical information concepts carries over to the quantum domain. However, it has become clear that infinite‐dimensional quantum systems are also attractive candidates for quantum information ...
