Mixing doubly stochastic quantum channels with the completely depolarizing channel
It is proved that every doubly stochastic quantum channel that is properly averaged with the completely depolarizing channel can be written as a convex combination of unitary channels. As a consequence, we find that the collection of channels expressible as convex combinations of unitary channels has non-zero Borel measure within the space of doubly stochastic channels.
متن کاملA-Scrambling Exists!
The nature of scrambling is a focus of recent debate in the syntactic literature. The term scrambling is used to describe apparently optional permutations of word order, found especially in languages with extensive case-marking. Saito (1989) argues that scrambling is A-bar movement (like wh-movement), rather than A-movement (like movement to the subject position). Webelhuth (1989) argues for sc...
متن کاملVIEWPOINT Seeing Scrambled Spins
P hysicists have long wondered whether and how isolated quantum systems thermalize—questions that are relevant to systems as diverse as ultracold atomic gases and black holes. Recent theoretical and experimental advances are bringing fresh insight into this line of inquiry. At one extreme, researchers have shown that disorder can fully arrest thermalization in certain isolated many-body quantum...
متن کاملA note on scrambled Halton sequences
Halton’s low discrepancy sequence is still very popular in spite of its shortcomings with respect to the correlation between points of two-dimensional projections for large dimensions. As a remedy, several types of scrambling and/or randomizations for this sequence have been proposed. We examine empirically some of these by calculating their L4and L2-discrepancies (D* resp. T*), and by performi...
متن کاملSperm and scrambled eggs
A newspaper obituary not long ago revealed that its subject was believed to have been both the son and grandson of the lecherous monarch, Edward VII. (Work it out for yourself.) But this is as nothing to the conundrums that Lee Silver sets out in his mesmerizing vision of our genetic future. Within weeks of the eruption of Dolly the sheep into the pages of Nature — and regardless of the doubts ...
