ENTANGLEMENT VERSUS ENERGY IN MULTIQUBIT ENTANGLEMENT DYNAMICS PROBLEM
Feng Han, Yun‐Jie Xia
Abstract
We study the relation between energy and entanglement in a multiqubit entanglement dynamics problem in cavity QED. The model consists of three two-level atoms A, B and C which are initially prepared in a Greenberger–Horne–Zeilinger-like state and locally coupled with independent cavities a, b and c, respectively. We shall show that the dynamical evolution of atomic entanglement is closely related to that of their energy.
