QUROPE Quantum Information Processing and Communication in Europe

QUCHIP – Quantum Simulation on a Photonic Chip is a FET-ProActive project funded under the call FETPROACT-3-2014: Quantum simulation.

The goal of QUCHIP is to study applications of quantum walks in simulating quantum phenomena.

QUCHIP involves 9 European Universities and Research Centres from 5 different European countries.

MULTI replaces the familiar sequential model of computation that uses Boolean variables and combinational gates by logic operations that are executed in parallel on devices that have a built-in many state memory and whose inputs and outputs are multivalued. MULTI seeks to design, simulate and experimentally implement proof of principle devices on the atomic and molecular scale.

The ultimate aim of the proposed research is to make ultra-sensitive matter-interferometry available in a compact and eventually portable device. Specifically, we seek to test the ideas in a guided matter-wave interferometer based on ultracold bosonic atoms. We will explore matter-wave interferometry in macroscopic traps as well as on atom-chips. Such device has the potential to induce a step change in the sensitivity with which acceleration and rotation can be measured. The expected impact extends well beyond fundamental research, for example to geoscience and navigation.

We will study the algorithmic aspects of quantum information. Our goal is to find new algorithms for quantum computers and new quantum communication protocols that are more efficient than the classical protocols. We will pursue this goal in a number of different ways.

Quantum phenomena are an important basis for future information processing and information acquisition technologies. They will become particularly relevant for quantum-enhanced metrology and advanced sensors, which exploit the quantum superposition principle at a mesoscopic scale.

AtMol will establish comprehensive process flow for fabricating a molecular chip, i.e. a molecular processing unit comprising a single molecule connected to external mesoscopic electrodes with atomic scale precision and preserving the integrity of the gates down to the atomic level after the encapsulation. Logic functions will be incorporated in a single molecule gate, or performed by a single surface atomic scale circuit, via either a quantum Hamiltonian or a semi-classical design approach.

The LIMA project exploits cutting edge photonic technologies to enhance silicon solar cell efficiencies with new concepts in nanostructured materials. It proposes nano-structured surface layers designed to increase light absorption in the solar cell while decreasing surface and interface recombination loss. Integration in a back contact design further reduces these interface losses and avoids shading.

The aim of PROMISCE is to provide the foundations for a novel research field: propagating quantum microwave technologies in strongly and ultra-strongly coupled environments. In particular, its potential for scalable quantum information and communication technology (Q-ICT) applications will be demonstrated. PROMISCE is born from a challenging and controversial idea, which is that microwave photons can interact strongly among each other and with their environment even in the absence of confining cavities.

Quantum technologies promise to revolutionise our digital world providing security in communications and solutions for what have been thought of as unsolvable computational problems. The project QWAD introduces the technology of laser-written integrated optics, a powerful new tool for next generation quantum communications and computing, solving critical problems in terms of scalability and reliability. This disruptive photonic technology will speed up the evolution from lab systems to real world applications.

This project will establish a groundbreaking research program in hybrid quantum systems combining solid state and atomic components. The key elements in this project are devices based on single quantum dots and novel photon storage schemes in atomic systems. Quantum dots, also known as artificial atoms, enable photon generation in the solid state with functionalities such as tunability, high collection efficiency, radiative lifetime engineering and scalability.
