A Note on Time-Optimal Transfer of Coherence [PDF]
A. Carlini, T. KoikeWe provide exact analytical solutions for the problem of time-optimal transfer of coherence from one spin polarization to a three-fold coherence in a trilinear Ising chain with a fixed energy available and subject to local controls with a non negligible time cost. The time of transfer is optimal and consistent with a previous numerical result obtained assuming instantaneous local controls.View original: http://arxiv.org/abs/1209.0405
