Metrology using atoms in an array of double-well potentials
Danish Ali Hamza, Jan Chwedeńczuk
Quantum effects, such as entanglement, Einstein-Podolsky-Rosen steering, and Bell correlations, can enhance metrological sensitivity beyond the standard quantum limit. These correl…

Bell correlations of a thermal fully-connected spin chain in a vicinity of a quantum critical point
Danish Ali Hamza, Jan Chwedeńczuk
Bell correlations are among the most exotic phenomena through which quantum mechanics manifests itself. Their presence signals that the system can violate the postulates of local r…
