Harnessing quantumness of states using discrete Wigner functions under (non)-Markovian quantum channels

Jai Lalita, K. G. Paulson, Subhashish Banerjee

The negativity of the discrete Wigner functions (DWFs) is a measure of non-classicality and is often used to quantify the degree of quantum coherence in a system. The study of Wign…
