Ty Volkoff: Schrodinger cat states in separable Hilbert space: optimal branch distinguishability and algebras for metrological usefulness
Ty Volkoff, University of California, Berkeley
Two measures of macroscopicity for quantum superpositions in countably infinite dimensional Hilbert space will be introduced: one depending on the optimal distinguishability of the components of the superposition under measurements of subsets of particles and another based on the ratio of the quantum Fisher information of the superposition to that of its components.
