Hello everyone,

I would like to draw your attention to the STARS postdoctoral programme just launched at the Barcelona Supercomputing Center, which includes the QUANTIC group led by Prof. J. I. Latorre and myself.

STARS programme aims at fostering the training of highly skilled post-doc in all fields of High Performance Computing and related applications, including Quantum Computation theory and experiment.

The programme will award 20 outstanding post-doctorate researchers of all nationalities with 24-month INCOMING fellowships, providing them with all necessary tools for developing their potentials, deepening their skills and knowledge in a stimulating, international and interdisciplinary environment, and offering them intersectorial short secondments (1-3 months) with private industry or non-academic research centres (such as Lenovo, CISCO, AstraZeneca, IBERDROLA, EU JRC, AEMET, IRB and CRG in order to boost their career perspectives as successful independent researchers. Short secondments periods under the premises of these partner institutions will take place within the STARS programme. Fellows will also be strongly encouraged to participate at least once a year in an international event in their domain of research.

Here is a list of projects and groups available.

Dear all,

the Spanish Network on Quantum Information and Quantum Technologies is now officially approved. This excellence network is funded by MINEICO through the Agencia Estatal de Investigación, starting on July 1st 2017 and with a duration of two years.

All groups in Spain that work in the field of quantum technologies are welcome to join this new edition of the network, if they have not already done so.

With this message I would like to encourage you to participate in the upcoming activities of the network, as well as to involve the network in any activities that you have planned. While part of the budget is reserved for the 5th edition of the ICE workshops, the network supports smaller events, such as the workshop on Trapped Ion Experiments and Foundations on Quantum Theory in Granada, or other outreach activities. Please contact the network organization if you need further details.
