We prove the security of the 1984 protocol of Bennett and Brassard (BB84) for quantum key distribution. We first give a key distribution protocol based on entanglement purification, which can be proven secure using methods from Lo and Chau's proof...

Se qualcuno ha mai letto il mio Nick prima d’ora, potrebbe essere successo che sapete che io non sono un fan di Aston Martin, per niente proprio, qualsiasi aston dopo il 1930 (circa) personalmente, ...
A correlation inequality is derived from local realism and a supplementary assumption. This inequality is violated by a factor of 1.5 in the case of real experiments, whereas previous inequalities such as Clauser-Horne-Shimony-Holt inequality of 19...
Young's inequality may refer to: Young's inequality for products, bounding the product of two quantities Young's convolution inequality, bounding the
Look up inequality or ≠ in Wiktionary, the free dictionary. Inequality may refer to: Inequality (mathematics), a relation between two quantities when
We present a detection scheme which using imperfect detectors, and imperfect quantum copying machines (which entangle the copies), allows one to extract more information from an incoming signal, than with the imperfect detectors alone....
Suppose we are given an entangled pair and then one can ask how well we can produce two entangled pairs starting from a given entangled pair using only local operations. To give response of the above asked question, we study broadcasting of entangl...
We find that very different quantum copying machines are optimal depending on the indicator used to assess their performance. Several quantum copying machine models acting on non-orthogonal input states are investigated, and assessed according to t...

We prove a general upper bound on the tradeoff between time and space that suffices for the reversible simulation of irreversible computation. Previously, only simulations using exponential time or quadratic space were known. The tradeoff shows f...
We review the theory of continuous-variable entanglement with special emphasis on foundational aspects, conceptual structures, and mathematical methods. Much attention is devoted to the discussion of separability criteria and entanglement propertie...

Just picked up a GB splitting maul and was looking at it more closely at home. Is this a typical fit and finish for these guys? The bit is pretty off and the grinds on the sledge are super sloppy. I u...

We define and show how to construct nonbinary quantum stabilizer codes. Our approach is based on nonbinary error bases. It generalizes the relationship between selforthogonal codes over $GF_{4}$ and binary quantum codes to one between selforthogona...
