Minimal optimal generalized quantum measurements Latorre, José Ignacio Pascual, Pedro, 1934-2006 Tarrach, R., 1948- Teoria quàntica Teoria de camps (Física) Quantum mechanics Field theory (Physics) Optimal and finite positive operator valued measurements on a finite number N of identically prepared systems have recently been presented. 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. 2010-06-08T09:38:36Z 2010-06-08T09:38:36Z 1998 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0031-9007 https://hdl.handle.net/2445/12792 146067 eng Reproducció digital del document publicat en format paper, proporcionada per APS i http://dx.doi.org/10.1103/PhysRevLett.81.1351 Physical Review Letters, 1998, vol. 81, núm. 7, p. 1351-1354 http://dx.doi.org/10.1103/PhysRevLett.81.1351 (c) American Physical Society, 1998 info:eu-repo/semantics/openAccess 4 p. application/pdf American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
