Abstract
We present the results of computer simulations of dynamics of the quan tum Control-Not gate for the system of two spins connected by a weak I sing interaction. It is demonstrated that, for both ''digital'' and '' superposition'' initial conditions, a resonant pi-pulse can provide an adequate implementation of the quantum Contol-Not gate. We also consi der the influence of slightly non-resonant pi-pulse and noise on the d ynamics of the quantum Control-Not gate.
