Density Operators and Quasiprobability Distributions
The problem of expanding a density operator p in forms that simplify the evaluation of important classes of quantum-mechanical expectation values is studied. The weight function P(n) of the P representation, the Wigner distribution W(o), and the function (n ~ p ~o), where ~n) is a coherent state, are discussed from a unified point of view. Each of these quasiprobability distributions is examine...
متن کاملOn Discrete Quasiprobability Distributions
Due to the recent development of hardware facilities, the description of the state and evolution of the wave processes has also evolved. In addition to the configuration space description and Fourier analysis, it has now become possible to use the Quasiprobability distributions that describe the state of the wave process in phase space of the corresponding mechanical system. By wave process we ...
متن کاملNonclassicality criteria: Quasiprobability distributions and correlation functions
We use the exact calculation of the quantum mechanical, temporal characteristic function χ (η) and the degree of second-order coherence g(2)(τ ) for a single-mode, degenerate parametric amplifier for a system in the Gaussian state, viz., a displaced-squeezed thermal state, to study the different criteria for nonclassicality. In particular, we contrast criteria that involve only one-time functio...
متن کاملCompression of sources of probability distributions and density operators
We study the problem of efficient compression of a stochastic source of probability distributions. It can be viewed as a generalization of Shannon’s source coding problem. It has relation to the theory of common randomness, as well as to channel coding and rate–distortion theory: in the first two subjects “inverses” to established coding theorems can be derived, yielding a new approach to provi...
متن کاملEigenvalue Bounds on Quasiprobability Distributions and Experimental Tests of Quantum Mechanics
Best possible upper and lower bounds, as defined by quantum mechanics through theWigner function, are determined for the quasiprobability mass which can occur on any circular disk or annulus in the phase-plane of a 1-dimensional system in an arbitrary state. Violation of these bounds by experimentally measured quasiprobability distributions would signal deviations from quantum mechanics. In rec...
