Geometric uncertainty relation for quantum ensembles
Hoshang Heydari, Ole Andersson
Geometrical structures of quantum mechanics provide us with new insightful results about the nature of quantum theory. In this work we consider mixed quantum states represented by…

A Symmetry Approach to Geometric Phase for Quantum Ensembles
Ole Andersson, Hoshang Heydari
We use tools from the theory of dynamical systems with symmetries to stratify Uhlmann's standard purification bundle and derive a new connection for mixed quantum states. For unita…
