Multi-setting Bell inequality for qudits
Se-Wan Ji, Jinhyoung Lee, James Lim +2
We propose a generalized Bell inequality for two three-dimensional systems with three settings in each local measurement. It is shown that this inequality is maximally violated if…
Proposal for direct measurement of concurrence via visibility in a cavity QED system
Sang Min Lee, Se-Wan Ji, Hai-Woong Lee +1
An experimental scheme is proposed that allows direct measurement of the concurrence of a two-qubit cavity system. It is based on the cavity-QED technology using atoms as flying qu…
Scalable cavity-QED-based scheme of generating entanglement of atoms and of cavity fields
Jaehak Lee, Jiyong Park, Sang Min Lee +2
We propose a cavity-QED-based scheme of generating entanglement between atoms. The scheme is scalable to an arbitrary number of atoms, and can be used to generate a variety of mult…
Additional information decreases the estimated entanglement using the Jaynes principle
Koji Nagata
We study a particular example considered in {[Phys. Rev. A {\bf 59,} 1799 (1999)]}, concerning the statistical inference of quantum entanglement using the Jaynes principle. Assume…
