| contents | We study entanglement degradation when noise on one share of an entangled pair is described by the dissipative Landau-Zener model. We show that spin-coupling direction to the environment significantly affects entanglement dynamics. In particular, for zero bath temperature in the slow-driving regime with transversal coupling, entanglement remains intact and in the fast-driving regime transversal noise have less destructive affects on entanglement compared to the longitudinal noise. Furthermore, we show that non-adiabatic dynamic is more in favour of preserving entanglement compared to adiabatic evolution. |
