Poisson-Schrodinger problem
Opis:: We present a numerical solution of the Poisson-Schrodinger problem for a semiconductor nanostructure containing a single quantum dot. The main outcome of our work is the lateral confinement potential, which determines the electronic properties of the nanodevice. We study the real nanodevice with cylindrical symmetry, which allows us to solve the three-dimensional problem on a two-dimensional mesh. We discuss the self-consistency of the solution with respect to the distribution of ionized donors inside the nanodevice.

Opis:: We discuss a possible realization of a quantum controlled-NOT gate with the use of two coupled quantum dots. Transitions between quantum states of a computational basis are driven by the microwave π-pulse. The parameters of the proposed nanodevice have been optimized in order to make the operation cycle of the gate as short as possible. Numerical solutions of the time-dependent Schrodinger equation allow us to simulate transitions between the quantum states which correspond to the subsequent stages of the gate's operation. The performed time-dependent simulations are a test of realizability of the quantum controlled-NOT gate in the nanodevice.
