Experiment

The group studies atomic and molecular quantum systems with respect to their interactions on different levels of complexity. Of special importance is the application and extension of modern methods for the manipulation and quantum control to many-body quantum systems, in particular using coherent light. The systems under investigation range from highly excited Rydberg atoms over atomic and molecular quantum gases to molecular aggregates. The group develops technologies for trapping and cooling of neutral atoms as well as quantum-state sensitive diagnostics.

The section on Quantum Physics and Information Technology at the Physics department of DTU (Technical University of Denmark) is headed by Prof. Ulrik Lund Andersen and conducts experimental research into - among other things - optical quantum information technology, quantum sensing with diamond and mechanical oscillators, and nano-optics.

Atoms are the building blocks of all matter. They have a positively charged nucleus and electron clouds define their outer boundaries. In nature, they remain electrically neutral. The number of electrons governs their chemical properties. All these have long been studied and exploited by mankind. Yet we are just now learning a whole new way of communicating with atoms, and 2 Nobel prizes were given as a result in 1997 and 2002. The atom chip is a chapter in this new dictionary - translating from human language to atom language. This journey may lead to new insights into the foundations of quantum theory, and numerous technological applications.

We work on applications of quantum optical techniques to spectroscopy and imaging.

We are an experimental research group located at the University of Cambridge, Cavendish Laboratory. Our primary focus area is Spin-Based Quantum Information Science and Nanoscale Quantum Metrology. For this purpose we are interested in the study and control of spins confined in mesoscopic quantum systems, as well as the interface of spin and photon states.

Developers of ARTIQ, a next-generation control system for quantum information experiments.

Our activities in quantum information concentrate on the implementation of simple quantum algorithms and the development of techniques for reducing decoherence and errors. Our experimental setups include magnetic resonance and high-resolution laser systems.

The chair for Semiconductor Quantum Nanosystems led by Jonathan Finley explores a wide range of topics related to the fundamental physics of nanostructured materials and their quantum-electronic and -photonic properties. Members of the institute study the unique electronic, photonic and quantum properties of materials patterned over nanometer lengthscales and explore how sub-components can be integrated together to realise entirely new materials with emergent properties.
