Scheme for generating a cluster-type entangled squeezed vacuum state via cavity QED
Jing-Ji Wen, Kyu-Hwang Yeon, Hong‐Fu Wang, Shou Zhang · Chinese Physics B · 2014
A scheme is proposed to generate an N -qubit cluster-type entangled squeezed vacuum state (CTESVS) based on the two-photon interaction between a two-level atom and the cavity fields with the cavity QED system. The CTESVS in N separate cavities can be effectively obtained after performing a simple one-qubit measurement on the atom. The influence of cavity decay on the CTESVS is also discussed.
