Detecting metrologically useful entanglement in the vicinity of Dicke states
Iagoba Apellaniz, Bernd Lücke, Jan Peise +2
We present a method to verify the metrological usefulness of noisy Dicke states of a particle ensemble with only a few collective measurements, without the need for a direct measur…

Detecting multiparticle entanglement of Dicke states
Bernd Lücke, Jan Peise, Giuseppe Vitagliano +4
Recent experiments demonstrate the production of many thousands of neutral atoms entangled in their spin degrees of freedom. We present a criterion for estimating the amount of ent…
