N2 - We propose a new method for creating an optimal coherence in a two-level system (TLS) based on adiabatic following. Optimal coherence is achieved by choosing the time-dependent phase of the pulse that provides vanishing field-TLS detuning δ (t) at central time when the pulse amplitude reaches maximum. For example, δ (t) = δ0 (1 - exp ((t - t0) / τ0))4 for t ≤ t0 and δ = 0 for t > t0. The pulse envelope used in calculations has Gaussian form such that the Rabi frequency is ΩR (t) = ΩR exp (- (t - t0)2 / τ02)), where τ0 is the pulse duration.
