Dear all,

in order to archive the information of this newsletter and in particular the publication lists, we have replaced the old-non-working website, by a very simple www.iontraps.eu

You will find a form for subscription to the newsletter, do not hesitate to forward it to your colleagues and students. If you receive this newsletter directly, no need to subscribe - of course!

There are still some holes in the website, information will be imported slowly. We will also try to have an actualized events and jobs list

News
 
ARTIQ (Advanced Real-Time Infrastructure for Quantum physics) is a next-generation control system for quantum information experiments. It is being developed by M-Labs  in partnership with the Ion Storage Group at NIST, and its applicability reaches beyond ion trapping. You will find details HERE

In memory of Professor Danny Segal, a special issue of the Journal of Modern Optics will be dedicated to his research interests and short reminiscences of him. Selected papers from the 2016 European Conference on Trapped Ions, with which Danny was closely associated, will form part of this special issue. More info
