Abstract:
1. An apparatus for distributing a sequence of symbols between an emitter station and a receiver station connected by a quantum channel and a conventional channel, the apparatus comprising: an emitter station having a control means so as to enable the emitter station to command and control its own components in cooperation with associated components of the receiver station and a quantum source for generating a stream of separate quantum systems, wherein the emitter station comprises a quantum system source controlled by a processing unit having a memory, as well as a data transmission and communications mechanism permitting communications with other components of the apparatus, in which the quantum system source generates a stream of qubits, wherein each qubit is made up of a pair comprising a first and a second pulsed weak coherent state of an electromagnetic field, each qubit including a time bin of duration t, the center of each of the time bin is separated by a time Ti, with t being smaller than T
