With physical realization in mind, we propose here optimal and minimal generalized quantum measurements for two-level systems. We explicitly construct them up to N = 7 and verify that they are minimal up to N = 5.4 p.application/pdfeng(c) American Physical Society, 1998Teoria quànticaTeoria de camps (Física)Quantum mechanicsField theory (Physics)info:eu-repo/semantics/article146067info:eu-repo/semantics/openAccess
