Shigeru Furuichi
TL;DR
This paper presents a new Schrödinger-type uncertainty relation that enhances the Heisenberg uncertainty principle for mixed quantum states using Wigner-Yanase skew information.
Contribution
It introduces an improved Schrödinger uncertainty relation specifically for mixed states, building on S. Luo's quantum uncertainty measure.
Findings
Stronger uncertainty bounds for mixed states
Enhanced understanding of quantum uncertainty measures
Improved theoretical framework for quantum information
Abstract
We shall give a new Schr\"odinger type uncertainty relation for a quantity representing a quantum uncertainty, introduced by S.Luo in \cite{Luo1}. Our result improves the Heisenberg uncertainty relation shown in \cite{Luo1} for a mixed state.
