Devices interact with each other and with the environment. For classical devices assigning boundary conditions at the physical exit and entry regions often satisfactorily treats this interaction. The situation with quantum devices is more involved. We have found that the effects of the device–device interaction require the specification of suitable phase space boundary conditions. We illustrate this with studies of one‐space dimension RTDs within the framework of the coordinate representation phase space.
