Dynamics of Quantum States in a System of 3 Quantum Dots with Dipole-Dipole Interaction

摘要： We present the results of simulation of the dynamics of a 3 quantum dot array by means of numerical solution of the von Neumann equation. The trace over the states of phonon bath was taken by Feynman path integral numerical calculation. It is shown that simplistic system of 3 quantum dots with common phonon bath can implement XOR logic operation. The results of our model can be applied to the development of different quantum simulators, quantum gates, and quantum neural networks implemented in arrays of quantum dots.
