This special issue of International Journal Of Quantum Information is aimed to collect papers addressing both fundamental problems and applications, thus offering to readers comprehensive and up-to-date overview on the characterization and use of quantum correlations. We welcome papers that address fundamental aspects of quantum and classical correlations in discrete and continuous variable systems, propose implementations to make quantitative measurements of quantum correlations, or describe experiments that exploit quantum correlations as a resource for quantum technology.

EU-funded scientists in the Netherlands have managed to rapidly control the building blocks of a quantum computer by using an electric field rather than a magnetic one. In addition, the team succeeded in embedding these building blocks, known as quantum bits or qubits, in a semiconductor nanowire. The study, published in the journal Nature, could lead to advances in the field of quantum computing and communication.

Quantum entanglement represents an invaluable resource for the emerging areas of quantum information and quantum technologies. The imperative towards faster processing of ever increasing quantities of data creates an arrow in the direction of multi-dimensional and multi-modal quantum entanglement. Generating entanglement of light and of light and matters in high dimensional Hilbert spaces paves the way to a breakthrough in the information capacity of QIPC protocols, and provide a fundamental resource for quantum metrology and quantum imaging.

Jon Cartwright at PhysicsWorld writes: ''Physicists in the US and the UK have found a way to store and read data in nuclear spins using electronic pulses. The breakthrough could help in the development of spintronic systems that process information using spins – and could also find applications in quantum computation.''
The Foundations of Probability and Physics-6 (FPP6) conference is arranged by ICMM, International Centre for Mathematical Modelling in physics, engineering and cognitive sciences, at Linnaeus University in Växjö, Sweden.
This is the 12th conference arranged by ICMM which is devoted to quantum foundations and quantum information, especially the clarification of fundamental questions. For previous conferences, see Lnu.se/research-groups/icmm/conferences?l=en.
Evidence that photosynthetic systems are capable of supporting quantum-coherent energy transport at high temperatures has generated controversy over the implications of such phenomena for biology and applications. This meeting will bring together leading scientists from photosynthesis, quantum information, and organic-polymer based research to discuss far-reaching consequences of these quantum effects in the design of novel, robust and efficient energy technologies.
Quantum computation, quantum communication, and quantum cryptography are topics of a new and interdisciplinary field in the intersection of computer science, information theory, and quantum mechanics. The aim of the TQC'11 conference is to allow deep coverage of new and original research on these topics and to raise important problems that can benefit from theoretical investigation and analysis.

Kate McAlpine at PhysicsWorld writes: ''Since quantum mechanics was first formulated, a string of physicists including Albert Einstein have been uncomfortable with the idea of entanglement – whereby a group of quantum particles have a closer relationship than allowed by classical physics. As a result, some physicists have proposed alternative theories that allow such close relationships without the need for quantum mechanics.

Chris Lee at ArsTechnics writes: ''Not so long ago, we reported on a paper that purported to blow a hole in quantum key distribution (QKD) systems. Now, researchers at Toshiba have struck back with findings that show that the attack doesn't really work. To which the original authors have replied, "Well, it depends." ''
