A procedure is discussed for creating coherent superpositions of motional states of ion strings. The motional states are across the structural transition linear-zigzag, and their coherent superposition is achieved by means of spin-dependent forces, such that a coherent superposition of the electronic states of one ion evolves into an entangled state between the chain's internal and external degrees of freedom. It is shown that the creation of such an entangled state can be revealed by performing Ramsey interferometry with one ion of the chain.

Dear Colleague,

we would like to draw your attention to the upcoming workshop on

"New trends in complex quantum system dynamics"

to be held in Cartagena, Spain on 8-12 April 2013.

The workshop homepage is: http://www.cqs.upct.es

The list of invited speakers includes (confirmed):

• The emergence of quantum information theory from quantum mechanics
• Many-body quantum simulation
• Qubits: Semiconductor quantum dots
• Quantum entanglement and teleportation
• Qubits: Josephson-junction devices
• Quantum communication, error correction
• Physical implementation of quantum computers
• Qubits: Optical and microwave photons
• Qubits: Majorana fermions

Two-week course with about 45 hours of lectures for students and young scientists

The discussions at and around the next summit of the European Union heads of states and governments, which is scheduled for 22 and 23 November, will be decisive in determining the EU research budget for the next seven years. Several Member States are demanding severe cuts on the total EU budget and research will have to compete with other policy priorities.

The Nobel Prize in Physics 2012 was awarded jointly to Serge Haroche and David J. Wineland "for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems".

Following QIPC2009 in Rome and QIPC2011 in Zurich we have the pleasure to announce another edition of the QUANTUM INFORMATION PROCESSING AND COMMUNICATION CONFERENCE – QIPC2013.

The reports are available for public download at the WP2 deliverables page. They contain a detailed description of the features that are integrated in the qurope.eu web site, that allow a classification and analysis of the database material that is relevant to QIPC.

We are very pleased to announce a thematic month on Quantum Information theory:

2013 is the “Year of Analysis” at the Institute of Mathematical Science, ICMAT (Madrid). As a part of the activities there will be a thematic period about QUANTUM INFORMATION THEORY* from 17^th June to 17^th July (2013).

This period will be divided into 4 topics (one week each):

We are pleased to announce the Winter School on Rydberg Physics and Quantum Information, to be held February 10-15, 2013 at the University Center Obergurgl, Austria.
