A simple analytical expression of quantum Fisher and Skew information and their dynamics under decoherence channels

Nour-Eddine Abouelkhir, Hanane EL Hadfi, Abdallah Slaoui +1

In statistical estimation theory, it has been shown previously that the Wigner-Yanase skew information is bounded by the quantum Fisher information associated with the phase parame…
