Characterizing and witnessing multipartite correlations: from nonlocality to contextuality PhD thesis
... In the seminal paper of 1935, Einstein, Podolsky and Rosen (EPR35) noticed for the first time the phenomenon of quantum entanglement, which ultimately lead to the formal definition of Nonlocality by J. Bell in 1964 (Bel64). This phenomenon of nonlocality tells that correlations observed among the ou ...

... creation of cat states of up to six atomic qubits. Each qubit’s state space is defined by two hyperfine ground states of a beryllium ion; the cat state corresponds to an entangled equal superposition of all the atoms in one hyperfine state and all atoms in the other hyperfine state.
