Scheme for Preparation of a Peculiar Type of Tripartite Entangled State via Thermal Cavity
Zhang Gang, Yang Ming, Zhuo‐Liang Cao · Communications in Theoretical Physics · 2008
We propose a simple scheme for the generation of a peculiar tripartite entangled state via thermal cavity. The peculiar tripartite entangled state shares features of the GHZ and W state simultaneously. The photon-number-dependent parts in the effective Hamiltonian are canceled with the assistance of a strong classical field, thus the scheme is insensitive to both the thermal field and the cavity decay. The only thing one needs to do is to modulate the interaction time only once.
