Genuine multipartite einstein-podolsky-rosen steering
We develop the concept of genuine N-partite Einstein-Podolsky-Rosen (EPR) steering. This
nonlocality is the natural multipartite extension of the original EPR paradox. Useful …

Experimental realization of Dicke states of up to six qubits for multiparty quantum networking
We report the first experimental generation and characterization of a six-photon Dicke state.
The produced state shows a fidelity of F= 0.56±0.02 with respect to an ideal Dicke state and …
