News
The Ion Traps Newsletter lives on!
For over more than a decade the ITN has been very successful in providing important information about news, events, jobs, and publications, thus bringing together the trapped ion community. This success is the result of the dedication of Martina Knoop, initiator and editor of the ITN, and Alejandro Bermudez, responsible for compiling the publications. Martina Knoop has moved on to new responsibilities and therefore announced her retirement as editor in the last newsletter.
Since many appreciated the content of the newsletter, it will be continued in the same format as before. The new editorial team is led by Naz Pourmalek, the CEO of Quantum Valley Lower Saxony (QVLS e.V.), while Alejandro will continue to provide the list of publications.
Please continue to send us your thoughts, events, news, seminars, jobs, and publications to iontrap.newsletter@gmail.com so that we can keep each other informed. In the future, we will strive to provide web forms for the submission of information to streamline the generation of the newsletter.
