Abstract

In this paper we present result of theoretical calculation of entanglement within a spin structure of Gd3N@C80 under the in uence of rectangular impulses. Research is conducted using general spin Hamiltonian within SSNQ (spin system of N-qubits). Calculation of entanglement with variable impulse is performed using the time-dependent Landau-Lifshitz-Gilbert equation with spin-spin correlation function. We show that long rectangular impulse (t=850ps) can be used for maintaining of entanglement value. This allows us to offer a new algorithm which can be used to reduce the challenge of decoherence to logical scheme optimization.
