27th Itzykson Conference : Fluctuations far from Equilibrium  


We are glad  to inform  you that  the  27th ITZYKSON CONFERENCE will be held  from Wednesday, the 31st of May in the morning, to Friday the 2nd of June at the Institut de Physique Theorique (IPhT), CEA Universite de Paris-Saclay.

This year the ITZYKSON CONFERENCE will be devoted to "Fluctuations far from  Equilibrium".

You can find more details on the web-page dedicated to this event:

We hope that the conference will attract the interest of many participants.  We would be grateful if you could register at :
This will take you a very little time  but it will be of great help to us for practical matters.

Best regards,

Tomohiro Sasamoto, Laure Sauboy and  Kirone Mallick.

Quantum networks : Entangled ions across the university campus Innsbruck   


Trapped ions are one of the leading systems to build quantum computers. To link multiple such quantum systems, interfaces are needed through which the quantum information can be transmitted. Until now, trapped ions were only entangled with each other over a few meters in the same laboratory. Researchers from the university of Innsbruck succeeded to entangle two trapped ions located in two labs separated  by 230 meters. These efforts have been supported by a theoretical model of a single trapped ion including most of experimental noise sources.

The model, developed at IPhT, provided a guidance for the experimentalists, showing for example what to expect when increasing the distance or helping to identify the most detrimental noise sources. With the entanglement of far away ions, Austrian researchers show that trapped ions are a promising platform for future quantum networks that span cities and eventually continents. The results have been published in Physical Review Letters. They have been highlighted by Editors’ Suggestion and a Synopsis in Physics.
