I . Joint probabilities of conjugate observables
We derive “Bell inequalities” in four dimensional phase space and prove the following “three marginal theorem” for phase space densities ρ(−→q ,−→p ), thus settling a long standing conjecture : “there exist quantum states for which more than three of the quantum probability distributions for (q1, q2), (p1, p2), (q1, p2) and (p1, q2) cannot be reproduced as marginals of a positive ρ(−→q ,−→p )”....
متن کاملWigner distributions and the joint measurement of incompatible observables
A theory of joint nonideal measurement of incompatible observables is used in order to assess the relative merits of quantum tomography and certain measurements of generalized observables, with respect to completeness of the obtained information. A method is studied for calculating a Wigner distribution from the joint probability distribution obtained in a joint measurement. 1 Quantum tomograph...
متن کاملCorrespondence Principle
The Correspondence Principle is the relation, which exists in certain economic models, between comparative statics of equilibria and the properties of out-of-equilibrium dynamics. The Correspondence Principle (CP) implies that one obtains unambiguous comparative statics by selecting equilibria with desirable dynamic properties. Generally, the CP determines comparative statics in models with a o...
متن کاملStrong Correspondence for HOPLA
We show that the operational semantics for HOPLA is in strong correspondence with its presheaf semantics [2, 1]. The proof is a fairly standard logical relations proof, exploiting the path semantics of the language [3, 4]. Strong correspondence can be proved for full HOPLA by making use of the path semantics to get a logical relations proof off the ground. We’ll use the notation J−K for the pat...
متن کاملQUANTUM MECHANICS WITH CHAOS: Correspondence Principle, Measurement and Complexity
The true dynamical randomness is obtained as a natural fundamental property of deterministic quantum systems. It provides quantum chaos passing to the classical dynamical chaos under the ordinary semiclassical transition, which extends the correspondence principle to chaotic systems. In return one should accept the modified form of quantum formalism (presented by the Schrödinger equation) which...
