QUROPE Quantum Information Processing and Communication in Europe

As many of you probably know, the EC has launched an online consultation to identify game-changing directions for future research in FET related technological domains. The purpose of this consultation is to initiate thinking about future proactive initiatives to be included in the next FET workprogramme for 2016 and 2017.

Christian Roos (OEAW.EX), talk: Schrödinger cat state spectroscopy with trapped ions'

Photonics is a promising platform for quantum technologies. However, photon sources and two-photon gates currently only operate probabilistically. Large-scale photonic processing will therefore be impossible without a multiplexing strategy to actively select successful events.

Storing information encoded in light is critical for realizing optical buffers for all-optical signal processing

Our research focuses on addressing and manipulating isolated quantum systems, with the following goals:

Due to their low mass, high quality factor, and good optical properties, silicon nitride (SiN) micromembrane resonators are widely used in force and mass sensing applications, particularly in optomechanics. The metallization of such membranes would enable an electronic integration with the prospect for exciting new devices, such as optoelectromechanical transducers.

Demonstrations of primitive information processing elements with quantum bits (qubits) have been
implemented in many systems, but the requirements for precise quantum control, along with fast classical
feed-forward (conditioning future operations on measurement results) has proved challenging.

Atomic clocks have been instrumental in science and technology, leading to innovations such as global
positioning, advanced communications, and tests of fundamental constant variation. Timekeeping precision
at 1 part in 1018 enables new timing applications in relativistic geodesy, enhanced Earth- and space-based
navigation and telescopy, and new tests of physics beyond the standard model.
