Abstract

A quantum key distribution (QKD) method for distributing quantum keys across at least one communication channel (18, 20) of a communication network (12) is described. The at least one communication channel (18, 20) connects at least two nodes (14, 16) of the communication network (12), wherein the at least two nodes comprise a first node (14) and a second node (16). The QKD method comprises the following steps:- determining, by means of the at least two nodes (14, 16), a common secret key, wherein the common secret key is a data key; and- determining, by means of each of the at least two nodes (14, 16), a series of quantum base states based on the common secret key, wherein the series of quantum base states corresponds to a common secret quantum key.Further, a communication method and a communication system (10) are described.
