Abstract

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 Ω_R (t) = Ω_R exp (- (t - t₀)² / τ₀²)), where τ₀ is the pulse duration.
