spelling Hybrid classical-quantum formulations ask for hybrid notionsBarceló, CarlosCarballo Rubio, RaúlGaray, Luis JavierGómez Escalante, Ricardo11 p. : gráf.We reappraise some of the hybrid classical-quantum models proposed in the literature with the goal of retrieving some of their common characteristics. In particular, first, we analyze in detail the Peres-Terno argument regarding the inconsistency of hybrid quantizations of the Sudarshan type. We show that to accept such hybrid formalism entails the necessity of dealing with additional degrees of freedom beyond those in the straight complete quantization of the system. Second, we recover a similar enlargement of degrees of freedom in the so-called statistical hybrid models. Finally, we use Wigner's quantization of a simple model to illustrate how in hybrid systems the subsystems are never purely classical or quantum. A certain degree of quantumness (classicality) is being exchanged between the different sectors of the theory, which in this particular unphysical toy model makes them undistinguishable. ©2012 American Physical SocietyFinancial support was provided by the Spanish MINECO through projects FIS2011-30145-C03-01 and FIS2011-30145-C03-02, by the Consolider-Ingenio 2010 Program CPAN(CSD2007-00042), and by the Junta de Andalucía through project FQM219.
