Jin‐Ming Liu, Yuzhu Wang
Abstract
In this paper, we present a scheme to generate a three-mode entangled state of an atomic Bose–Einstein condensate in a symmetric three-well potential by using controlled atomic elastic collisions. Then, by means of the method for calculating the formation entanglement of two qubits, we obtain the analytic expressions of the residual entanglement of the three-mode BEC entangled state.
