Dissipative engineering a tripartite Greenberger-Horne-Zeilinger state for neutral atoms
D. X. Li, H. W. Xiao, C. Yang +1
The multipartite Greenberger-Horne-Zeilinger (GHZ) states are indispensable elements for various quantum information processing tasks. Here we put forward two deterministic proposa…
Dissipation induced state in a Rydberg-atom-cavity system
Dong-Xiao Li, Xiao-Qiang Shao, Jin-Hui Wu +1
A dissipative scheme is proposed to prepare tripartite state in a Rydberg-atom-cavity system. It is an organic combination of quantum Zeno dynamics, Rydberg antiblockade and at…
Engineering steady Knill-Laflamme-Milburn state of Rydberg atoms by dissipation
Dong-Xiao Li, Xiao-Qiang Shao, Jin-Hui Wu +2
The Knill-Laflamme-Milburn (KLM) states have been proved to be a useful resource for quantum information processing [Nature 409, 46 (2001)]. For atomic KLM states, several schemes…
Noise-induced distributed entanglement in atom-cavity-fiber system
Dong-Xiao Li, Xiao-Qiang Shao, Jin-Hui Wu +1
The distributed quantum computation plays an important role in large-scale quantum information processing. In the atom-cavity-fiber system, we put forward two efficient proposals t…
Ground-state blockade of Rydberg atoms and application in entanglement generation
X. Q. Shao, D. X. Li, Y. Q. Ji +2
We propose a mechanism of ground-state blockade between two -type Rydberg atoms in virtue of Rydberg-antiblockade effect and Raman transition. Inspired by the quantum Zeno effec…
