Small Unextendible Sets of MUBs
Abstract: In quantum information, Mutually Unbiased Bases (MUBs) correspond to sets of pairwise complementary observables. The maximal number of such bases in a system of dimension d is d+1, and cons...

On Nonclassicality of Light
Abstract: Identifying the classical-quantum divide and quantifying nonclassicality are fundamental issues in quantum exploration. By use of the Wigner-Yanase skew information [Proc. Nat. Acad. Sci. U...
