Hybrid Cavity Quantum Electrodynamics with Atoms and Circuits (HYBRIDQED)
ERC Starting Independent Researcher Grant

The main goal of this project is to develop an interface between solid state quantum systems and atomic degrees of freedom. In particular we consider superconducting quantum electronic circuits and Rydberg atoms. We explore the basic properties of both systems and their interactions and evaluate the potential for developing this hybrid quantum information processing approach beyond the current state of the art.

Geometric phases, pumping, and dissipation in quantum devices (GEOMDISS)
EU Project (FET Open, ICT-2007.8.0)

We investigate how dissipation influences the geometric phases and geometric pumping in quantum solid-state devices and assess the role of geometric manipulations in future ICT applications. Since all realistic solid-state devices suffer from dissipation due to their coupling to an uncontrolled environment with many degrees of freedom it is crucial to understand how the geometric effects are modified and whether they are still useful.

Solid State Systems for Quantum Information Processing (SOLID)
EU Project (FET proactive 2: Quantum Information Foundations and Technologies, ICT-2009.8.2)

The SOLID project aims to develop small solid-state hybrid systems that are capable of performing elementary processing and communication of quantum information. This involves the design, fabrication and investigation solid state qubits, oscillators, cavities and transmission lines that can be combined to create hybrid devices. Such systems interface and connect different types of qubits for quantum data storage, qubit interconversion, and quantum communication. For more information click here...

Atomic Quantum Technologies (AQUTE)
EU Project (FET proactive 2: Quantum Information Foundations and Technologies, ICT-2009.8.2)

We develop quantum technologies based on atomic, molecular and optical (AMO) systems for scalable quantum computation and for entanglement-enabled technologies like metrology and sensing and we establish and exploit new interdisciplinary connections, coming from AMO physics.

Circuit and Cavity Quantum Electrodynamics (CCQED)
EU Project (Marie Curie Actions, ITN-2010 )

This network bridges the quantum electrodynamics of atoms or ions strongly interacting with light in resonators, and the emerging field of solid-state superconducting circuit quantum electrodynamics. Advanced techniques will be developed jointly with industry partners for the manipulation of a deterministic number of particles - atoms, ions or artificial atoms - with electromagnetic fields covering the microwave and the optical frequency spectrum.

Cavity Quantum Electrodynamics and Quantum Information Processing with Superconducting Circuits
SNSF Project (Division II: Mathematics, Natural and Engineering Sciences)

This project focus on our novel approach, known as circuit quantum electrodynamics, to investigate coherent matter-light interaction and its use for quantum information processing in a solid-state setting. Based on the previous successes on the single qubit and single photon level we will now explore new regimes in multi-qubit and multi-photon interactions in quantum systems with a number of fully controllable degrees of freedom. here...
