    "abstract": "We investigate numerically a single-pulse implementation of a quantum\nControl-Not (CN) gate for an ensemble of Ising spin systems at room\ntemperature. For an ensemble of four-spin ``molecules\u0027\u0027 we simulate the\ntime-evolution of the density matrix, for both digital and superpositional\ninitial conditions. Our numerical calculations confirm the feasibility of\nimplementation of quantum CN gate in this system at finite temperature, using\nelectromagnetic $\\pi$-pulse.",
