Dear all,

we are happy to announce that the new COST Action “Trapped Ions: Progress in classical and quantum applications” has been kicked-off in September. The Action is chaired by Markus Hennrich from Stockholm University accompanied by a management committee with representatives from more than 20 countries.
Different tools will be implemented in the upcoming weeks and months, and you will be kept informed through this newsletter.

A non-negligible part of our budget will be dedicated to exchange visits between groups for a duration of  5 to 90 days, in particular for early-career researchers. Application forms will only be available in November, but we encourage you already to plan your visits, take contacts and prepare the abstracts of the work you wish to carry out !!

The ECTI conference will be one of the first events of the Action, and we’ll have already more information by then !

Best regards,
your editorial team
