SUMMARY:ICFO | EMILIA WITKOWSKA 
CLASS:PUBLIC
DESCRIPTION:The second Quantum Revolution&rsquo\;s main objective lies in m
 ultipartite entangled states: their production\, storage\, certification\,
  and application. Such states\, i.e.\, many-body entangled and many-body B
 ell correlated states\, are essential resources for quantum-based technolo
 gies and quantum-enhancement metrology. As such\, a general protocol allow
 ing the controlled generation of such states is an extensive research dire
 ction in modern quantum science. Spin squeezing represents such a protocol
  paving the way for high-precision measurements.\nI will discuss two metho
 ds to obtain a regular arrangement of atoms in an optical lattice where al
 l the atoms share metrologically useful quantum correlations in the form o
 f spin squeezing. Such a spin-squeezed atomic crystal is obtained using bo
 sonic or fermionic atoms. In the first case\, the spin-squeezed atomic cry
 stal is produced by adiabatically raising an optical lattice in an interac
 ting two-component Bose-Einstein condensate. For fermions\, however\, it i
 s necessary to add the atom-light coupling to induce effective interaction
 s among atoms. The schemes could be directly implemented experimentally wi
 th state-of-the-art techniques.\n&nbsp\;
