Abstract: In this paper, we establish some Brauer-type bounds for the spectral radius of Hadamard product of two nonnegative tensors based on Brauer-type inclusion set, which are shown to be sharper than the existing bounds established… read more here.

Abstract: We consider an arbitrary von Neumann algebra with a finite trace as mathematical setup for a general quantum system. Three measures of dependence of states on measurements are presented. We indicate estimates of the mutual… read more here.

Abstract: In exploring the precision limits of quantum metrology, the quest for a tighter Heisenberg limit in real-world environments becomes a key challenge. For this reason, in this paper, we propose a tighter Heisenberg limit for… read more here.
