Estimation of Potentially Unphysical Maps
When standard methods of process (black-box) estimation are applied straightforwardly then it may happen that some sets of experimental data result in unphysical estimations of the corresponding channels (maps) describing the process. To prevent this problem, one can use the method of maximum likelihood (MML), which provides an efficient scheme for reconstruction of quantum channels. This schem...
متن کاملTemporary Grand Unified Theory in Unphysical World
Recently, a grand unification scenario in unphysical world has been proposed.1) The basic idea is as follows. Fields form multiplets under a unified gauge group and the gauge coupling unification originates from the gauge symmetry at a high-energy scale, as ordinary grand unified theories (GUTs).2), 3) Some members in multiples, however, are unphysical degrees of freedom, which are eliminated b...
متن کاملThe unphysical nature of “ Warp Drive ”
We will apply the quantum inequality type restrictions to Alcubierre’s warp drive metric on a scale in which a local region of spacetime can be considered “flat”. These are inequalities that restrict the magnitude and extent of the negative energy which is needed to form the warp drive metric. From this we are able to place limits on the parameters of the “Warp Bubble”. It will be shown that th...
متن کاملFock States of Flavor Neutrinos are Unphysical
It is shown that it is possible to construct an infinity of Fock spaces of flavor neutrinos depending on arbitrary unphysical mass parameters, in agreement with the theory of Blasone and Vitiello in the version proposed by Fujii, Habe and Yabuki. However, we show that these flavor neutrino Fock spaces are clever mathematical constructs without physical relevance, because the hypothesis that neu...
متن کاملAn experimental test of noncontextuality without unphysical idealizations
To make precise the sense in which nature fails to respect classical physics, one requires a formal notion of classicality. Ideally, such a notion should be defined operationally, so that it can be subject to direct experimental test, and it should be applicable in a wide variety of experimental scenarios so that it can cover the breadth of phenomena thought to defy classical understanding. Bel...
