A Differential-Geometric Approach to Quantum Ignorance Consistent with Entropic Properties of Statistical Mechanics
In this paper, we construct the metric tensor and volume for the manifold of purifications associated with an arbitrary reduced density operator [Formula: see text]. We also define a quantum coarse-graining (CG) to study the volume where macrostates are the manifolds of purifications, which we call...
