✦ Synopsis

We apply the theory for the transmission probability T( ) through small interacting systems, which was formulated based on the Kubo formalism in the previous study, to a series of quantum dots described by the N -impurity Anderson model. SpeciΓΏcally, we calculate T( ) for N = 2 with the order U 2 self-energy and vertex corrections which satisfy the current conservation, and examine the two di erent parameter regions at t Β‘ and t ΒΏ . Here t is the inter-dot transfer and is the level broadening caused by the coupling with the noninteracting leads.

A new entropic measure of interdependence among quantum systems is introduced, and applied successfully to partitioning of a quantum register consisting of an array of quantum dots, according to the bit pattern of the register. In classical systems the degree of interdependence among partial systems
