Continuous-variable quantum key distribution with non-Gaussian quantum catalysis [PDF]

open access: yesPhys. Rev. A 99, 032327 (2019), 2018
The non-Gaussian operation can be used not only to enhance and distill the entanglement between Gaussian entangled states, but also to improve quantum communications. In this paper, we propose an non-Gaussian continuous-variable quantum key distribution (CVQKD) by using quantum catalysis (QC), which is an intriguing non-Gaussian operation in essence ...

Spiers Memorial Lecture: Interplay of theory and computation in chemistry—examples from on-water organic catalysis, enzyme catalysis, and single-molecule fluctuations [PDF]

open access: yes, 2010
In this lecture, several examples are considered that illustrate the interplay of experiment, theory, and computations. The examples include on-water catalysis of organic reactions, enzymatic catalysis, single molecule fluctuations, and some much earlier

On Kinetic Constraints That Catalysis Imposes on Elementary Processes [PDF]

open access: yesarXiv, 2023
Catalysis, the acceleration of product formation by a substance that is left unchanged, typically results from multiple elementary processes, including diffusion of the reactants toward the catalyst, chemical steps, and release of the products. While efforts to design catalysts are often focused on accelerating the chemical reaction on the catalyst ...

Deactivation and Regeneration of Mo/ZSM-5 Catalysts for Methane Dehydroaromatization

open access: yesEurasian Chemico-Technological Journal, 2010
The methane dehydroaromatization (DHA) was studied over a series of impregnated Mo/ZSM-5 catalysts with different molybdenum contents (1-10 wt.%). It was shown that total methane conversion was decreased by 30% during 12 h of DHA reaction.

Inverse Magnetic Catalysis in Nambu--Jona-Lasinio Model beyond Mean Field [PDF]

open access: yesPhys. Lett. B 758, 195-199 (2016), 2016
We study inverse magnetic catalysis in the Nambu--Jona-Lasinio model beyond mean field approximation. The feed-down from mesons to quarks is embedded in an effective coupling constant at finite temperature and magnetic field. While the magnetic catalysis is still the dominant effect at low temperature, the meson dressed quark mass drops down with ...
