Entanglement generation in harmonic chains: Tagging by squeezing

We address the problem of springlike coupling between bosons in an open-chain configuration where the counter-rotating terms are explicitly included. We show that fruitful insight can be gained by decomposing the time-evolution operator of this problem into a pattern of linear-optics elements. This allows us to provide a clear picture of the effects of the counter-rotating terms in the important problem of long-haul entanglement distribution. The analytic control over the variance matrix of the state of the bosonic register allows us to track the dynamics of the entanglement. This helps in designing a global addressing scheme, complemented by a proper initialization of the register, which quantitatively improves the entanglement between the extremal oscillators in the chain, thus providing a strategy for feasible long-distance entanglement distribution.

Elafin prevents lipopolysaccharide-induced AP-1 and NF-kB activation via an effect on the ubiquitin-proteasome pathway

In this paper we follow on from our research into SLPI by assessing the immunomodulatory activity of elafin - an antiprotease related to SLPI and also present on the respiratory tract. We demonstrate for the first time that exogenously applied elafin inhibits lipopolysaccharide-induced activation of the NF-kappaB and AP-1 pathways in monocytes. I designed this project and supervised Marcus Butler during his MD thesis.
