CP-Asymmetry: Observables and Minimal Theoretical Input
Penguin contributions, being not negligible in general, can hide the information on the CKM angle α coming from the measurement of the timedependent B0(t) → π+π− CP-asymmetry. Nevertheless, we show that this information can be summarized in a set of simple equations, expressing α as a multi-valued function of a single theoretically unknown parameter, which conveniently can be chosen as a well-d...
متن کاملNear Minimal Weighted Word Graphs for Post-processing Speech
Large vocabulary speech recognition applications can benefit from an efficient data structure for representing large numbers of acoustic hypotheses compactly. Word graphs or lattices generated by acoustic recognition engines are generally not compact and must be post-processed to keep lattice sizes small; however, algorithms designed for this task need to reduce the size of the lattice without ...
متن کاملApproximate joint measurements of qubit observables
Joint measurements of qubit observables have recently been studied in conjunction with quantum information processing tasks such as cloning. Considerations of such joint measurements have until now been restricted to a certain class of observables that can be characterized by a form of covariance. Here we investigate conditions for the joint measurability of arbitrary pairs of qubit observables...
متن کاملNotes on Joint Measurability of Quantum Observables
For sharp quantum observables the following facts hold: (i) if we have a collection of sharp observables and each pair of them is jointly measurable, then they are jointly measurable all together; (ii) if two sharp observables are jointly measurable, then their joint observable is unique and it gives the greatest lower bound for the effects corresponding to the observables; (iii) if we have two...
متن کاملI . 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 )”....
