Quantum memories are essential elements for many potential applications of quantum technology. Research on the development of such memories is currently very lively, with a particular emphasis on memories that can interface with photons, which are the best carriers of quantum information over long distances. A Colloquium paper in the May issue on EPJ D reviews a number of different approaches to this challenge, with a focus on the approaches that were represented in the large European Union Integrated Project "Qubit Applications". This Colloquium covers solid-state atomic ensembles, nitrogen-vacancy centres, quantum dots, single atoms and atomic gases. Since the considered approaches are very diverse, an important part of the work was to establish criteria that allow a meaningful comparison. The authors discuss both the current experimental state of the art and the potential long-term performance of the various systems.

Multi-mode optical systems can improve precision measurements in the domain of quantum imaging and metrology. In this context, mastering quantum fluctuations and correlations in complex optical systems is crucial. In a recent EPJ D paper, the authors G. Patera, N. Treps, C. Fabre and G.J. de Valcárcel present the quantum model for an optical parametric oscillator synchronously pumped by a mode locked laser. To cope with the complexity of a system that usually involves about 100 000 modes, the authors introduce new physical objects that they call supermodes, which are proper combinations of standard modes. Their dynamics is studied from both a classical and a quantum point of view with respect to the experimental condition considered. This study shows that a synchronously pumped optical parametric oscillator is a suitable and malleable source of highly multimode non-classical light in the temporal domain.

We are pleased to announce that from January 2010 Nigel Mason, Professor of Physics at the Open University, UK, will be leading EPJ D, together with Kurt Becker and Claude Fabre. Nigel Mason brings to the journal an interdisciplinary approach to the AMOP field. His research covers a wide range of AMOP topics spanning physics and chemistry including astrochemistry, atmospheric science, surface science and spectroscopy. Since the 1990s he has studied the spectroscopy of over 100 molecules (mainly of atmospheric interest) using synchrotron radiation quantifying their photolysis rates and global warming potential. Research on the formation of molecules by irradiation of low temperature (20K) ices has led to a new research programme exploring processes on planetary systems and in the interstellar medium. Most recently his research has extended to study radiation damage processes within biomolecular systems including DNA.

Using the time of detection of each single photon, the authors falsify a class of non-ergodic local models that have not been tested in previous experiments on the Bell inequality.

As of July 2009 The European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics has a third Editor-in-Chief. Kurt H. Becker (NYU-Poly) has been appointed and will work alongside Franco Gianturco and Claude Fabre, toward strengthening EPJ D. His particular emphasis will be on low-temperature plasma physics.

EPJ D broadens its scope in plasma physics by merging with the Czechoslovak Journal of Physics (CJoP) as of January 1st, 2007. CJoP is presently published by the Institute of Physics of the Czech Academy of Sciences and distributed by Springer. Publishing in all areas of physics CJoP is particularly active in the field of plasma physics. To reflect this new emphasis in scope, EPJ D has recently changed its subtitle from "Atomic, Molecular and Optical Physics" to "Atomic, Molecular, Optical and Plasma Physics". Acta Physica Hungarica B - Quantum Electronics is also merging.

EPJ D supports and endorses the European Commission's new Quantum Information Classification Scheme (QICS) which, in the field of quantum information sciences, both extends and complements the well-known PACS scheme. For accepted EPJ D articles relevant to the subject matter, the Editorial Office of EPJ D will kindly invite authors to provide appropriate QICS codes in addition to the usual PACS codes.
