Introduces a localization probability lambda for quantum states in subspaces that is stricter than standard overlap Tr(P rho), derived from Schur complement operator decomposition and possessing concavity and super-additivity.
□ It can be noted that in the clause 7 nothing is assumed about the positivity ofB ′, still whenever ran(B ′)⊆V,A+B ′ ≥0 impliesB+B ′ ≥0
