Variance-based uncertainty relations
arXiv:1012.3105 · doi:10.1103/PhysRevA.86.024101
Abstract
Uncertainty relations are fundamental in quantum mechanics. Here I propose state-independent variance-based uncertainty relations for two or more arbitrary observables in finite dimensional spaces. The uncertainty relations provide near-optimal lower bounds in some typical examples, and are useful for entanglement detection.
