Integrated Column Designs for Minimum Energy and Entropy Requirements in Multicomponent Distillation
An automated method, based on the Hewlett-Packard ORCA (Optimized Robot for Chemical Analysis) system, for sample preparation and analysis of petroleum samples by simulated distillation (SIMDIS) is described. Results obtained for the robotically prepared samples show excellent agreement with those obtained from the same samples prepared manually. The application, based on ASTM method D 2887, is...
Event 677 Distillation Absorption2010
The basic principle of entanglement processing says that entanglement cannot increase under local operations and classical communication. Based on this principle, we show that any entanglement measure E suitable for the regime of a high number of identically prepared entangled pairs satisfies ED < or = E < or = EF, where ED and EF are the entanglement of distillation and formation, respectively...
We prove the unconditional security of the Bennett 1992 protocol, by using a reduction to an entanglement distillation protocol initiated by a local filtering process. The bit errors and the phase errors are correlated after the filtering, and we can bound the amount of phase errors from the observed bit errors by an estimation method involving nonorthogonal measurements. The angle between the ...
We study the secrecy properties of Gaussian states under Gaussian operations. Although such operations are useless for quantum distillation, we prove that it is possible to distill a secret key secure against any attack from sufficiently entangled Gaussian states with nonpositive partial transposition. Moreover, all such states allow for key distillation, when Eve is assumed to perform finite-s...
