摘要：

We present the results of computer simulations of dynamics of the quantum Control-Not gate for the system of two spins connected by a weak Ising 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 consider the influence of slightly non-resonant pi-pulse and noise on the dynamics of the quantum Control-Not gate.
