QUROPE Quantum Information Processing and Communication in Europe

The QUIE2T architecture is structured around a set of four Virtual Institutes (VIs), mapped to the major QIPC sub-domains:

Virtual Institute of Quantum Computation

This institute will integrate all groups which have an effort aiming at building a large scale quantum computer, independently of the physical system used for this purpose. The latter will thus include trapped ions and neutral atoms, cavity QED, solid state devices (such as superconducting qubits, possibly in combination with circuit cavity QED, and spin qubits), all-optical devices, as well as impurity spins in solids, single molecular magnets, and all sort of hybridization between these different implementations.

Virtual Institute of Quantum Communication

Quantum Communication can be defined as the art of transferring quantum states from one place to another. The general idea is that quantum states encode quantum information: hence quantum communication also implies transmission of quantum information. Quantum Communication covers aspects of basic physics as well as of practical relevance (e.g., quantum key distribution protocols and quantum cryptography). Additionally, it takes care of the whole 'wiring' inside a quantum computer, i.e., contribute to quantum interfaces and repeaters. This institute will incorporate all groups working on the subject.

Virtual Institute of Quantum Information Theory

This Institute will comprise all theoretical efforts in the field. In fact, the development of QIPC has been driven by theoretical work of scientists working on the boundary between Physics, Computer Science, Mathematics, and Information Theory. In the early stages of this development, theoretical work has often been far ahead of experimental realization of these ideas. At the same time, theory has provided a number of proposals of how to implement basic ideas and concepts from quantum information in specific physical systems. These ideas are now forming the basis for successful experimental work in the laboratory, driving forward the development of tools that will in turn form the basis for all future technologies which employ, control and manipulate matter and radiation at the quantum level.

Virtual Institute of Quantum Technologies

Many branches of QIPC have gone past the proof-of-principle phase, and in the short term the first technological applications of quantum coherence and entanglement will appear. This institute will embrace all groups/industries working on the different aspects of these technologies which can be split into two main categories: either technologies that represent genuine applications of QIPC (e.g., quantum metrology, quantum imaging, quantum random number generators, etc.), or technologies instrumental in developing QIPC devices (e.g., single- and entangled-photon sources and detectors, chips for ion and atom traps, etc.)
