Description:
Author(s): D. Mogilevtsev, E. Garusov, M. V. Korolkov, V. N. Shatokhin, and S. B. Cavalcanti In this work an exactly solvable model of N two-level systems interacting with a single bosonic dephasing reservoir is considered to unravel the role played by collective non-Markovian dephasing. We show that phase estimation with entangled states for this model can exceed the standard quantum limit... [Phys. Rev. A 98, 042116] Published Tue Oct 16, 2018
