多粒子W态的绝热制备
Preparation of W class states of multiparticle by adiabatic passage
摘要
Abstract
We describe a novel technique for preparing the multiparticle W class states, which are based on adiabatic passage induced a suitably crafted time-dependent external field. We have derived the interaction Hamiltonian, and the adiabatic and diabatic evolution conditions of driving the system of n-spin-1/2 particles from initial unentangled state to the W class state. In addition, we show the diagram of the energies evolution and the populations of target state of transferring the system of three spin-1/2 particles from initial unentangled state to target entangled state of W-type.关键词
