Method and system for simulating quantum communication processes

Abstract

The present disclosure relates to a method and a system for simulating a quantum communication process. The method comprises the following steps: providing, in a data processing unit (10), quantum communication information for at least one quantum communication process to be simulated between at least a first quantum communication device (30), a second quantum communication device (31), and an eavesdropping device (33) via at least one quantum channel (32); determining, in the data processing unit (10) and from the quantum communication information, control data for a quantum processor (14) in which quantum operations are applied to quantum particles that are ions or neutral atoms and that are spatially controllable within several operational domains (21); and simulating the quantum communication process in the quantum processor (14) using the control data.In this process, each quantum bit of the quantum communication process is assigned to one of the quantum particles. Communication operations of the quantum communication process each correspond to at least one of the quantum operations, wherein the quantum operations include at least one first quantum operation for the first quantum communication device (30), at least one second quantum operation for the second quantum communication device (31), and at least one third quantum operation for the listening device (33). Furthermore, a noise process during the quantum communication process corresponds to at least one additional quantum operation.
