IMPRECISE MEASUREMENTS IN QUANTUM MECHANICS
... Physics, being an empirical science, is ultimately based on measurements. Scientific measurements require high expertise and sophisticated devices. In large part the progress of physics has been connected to the development of measurement techniques. Quantum theory has shown that measurements need a ...

Three Puzzles about Bohr`s Correspondence Principle

Such expressions might cause misunderstanding, since in fact—as we shall see later on—this Correspondence Principle must be regarded purely as a law of the quantum theory, which can in no way ...

Spin-orbit coupling effects in two
... The anisotropic exchange of coupled localized electrons has a convoluted history [19],[20],[21],[22],[23],[24],[25]. The question boils down to determining the leading order in which the spin-orbit coupling affects both the isotropic and anisotropic exchange. At zero magnetic field, the second order w ...

Characterizing and witnessing multipartite correlations: from nonlocality to contextuality PhD thesis
... In the seminal paper of 1935, Einstein, Podolsky and Rosen (EPR35) noticed for the first time the phenomenon of quantum entanglement, which ultimately lead to the formal definition of Nonlocality by J. Bell in 1964 (Bel64). This phenomenon of nonlocality tells that correlations observed among the ou ...

Defining and detecting quantum speedup
... consensus may be time- and community-dependent [14]. In the absence of a consensus about what is the best classical algorithm, we define potential (quantum) speedup as a speedup compared to a specific classical algorithm or a set of classical algorithms. An example is the simulation of the time evol ...

Generalized binomial distribution in photon statistics

For this reason, it would be a mistake to use the binomial distribution with any non-Poisson statistics. In the next Section the replacement for the binomial distribution is found ...

One then has to have something else, eg: • Gravitino - still decays, but lifetime may be much longer than the age of the universe • Hidden sector matter • Axion/axino The implications of each of these is that ( ...
