Equivalence between two-mode spin squeezed states and pure entangled states with equal spin

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/92643We prove that a pure entangled state of two subsystems with equal spin is equivalent to a two-mode spin-squeezed state under local operations except for a set of bipartite states with measure zero, and we provide a counterexample to the generalization of this result to two subsystems of unequal spin.6 pages, no figuresQuantum PhysicsEquivalence between two-mode spin squeezed states and pure entangled states with equal spintext
