Preparation of entangled squeezed states and quantification of their entanglement
Cai Xinhua, Kuang Le-Man · Chinese Physics · 2002
We propose a scheme for generating bipartite and multipartite entangled squeezed states via the Jaynes-Cummings model with large detuning. Bipartite entanglement of these entangled states is quantified by the concurrence. We also use the N -tangle to compute multipartite entanglement of these multipartite entangled squeezed states. Finally we discuss two limiting cases which arise from r →∞ and r →0, in which the multipartite entangled squeezed state reduces correspondingly into an N -qubit Greenberger-Horne-Zeilinger state and an N -qubit W state.
