Scalable multi-particle entanglement of trapped ions

H. Haeffner, W. Haensel, C. F. Roos +11

Among the various kinds of entangled states, the 'W state' plays an important role as its entanglement is maximally persistent and robust even under particle loss. Such states are…

Generalized spin squeezing inequalities in N qubit systems: theory and experiment

J. K. Korbicz, O. Gühne, M. Lewenstein +3

We present detailed derivations, various improvements and application to concrete experimental data of spin squeezing inequalities formulated recently by some of us [Phys. Rev. Let…
