Often we hear from young researchers that they have violated a Bell inequality with their new source by this and this factor. In such cases we usually forget about three basic underlying assumptions. Two of them are well known; Realism stating that outcomes of measurements exist before they are revealed in a measuring act and Locality forbidding superluminal communication between spatially separated laboratories. The third important assumption is Freedom exercised by the observers to choose their local measurements independently of each other.

The Electronics Materials Branch at the Naval Research Laboratory (NRL) in Washington, DC, seeks candidates for post doctoral positions in the theory of solid implementations for quantum information. Areas of current interest include quantum dots and coupled quantum dots, photons and microcavities, NV centers in diamond, quantum gates and decoherence.

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.
