We study the quantum physics of light
and matter, using the best tools available to modern science. We use ultra-cold atoms and ultra-high coherence photons to study exotic effects such as entanglement and squeezing. We are particularly interested in the interplay of optical, atomic, and quantum physics at the interface where these fields meet.

We investigate quantum optical and quantum information processes with cold atoms and non-classical light sources, especially quantum processes arising from light-atom interactions. Our main activities are in two related areas: manipulation of cold atomic ensembles, including spin squeezing and generation of atom-light entanglement, and generation of squeezed, entangled, and single-photon states of light at atomic resonance wavelengths.

Quantum theory is a huge success: it elegantly explains tiny atoms, molecules and photons, but also superconductors and white dwarf stars. It is also a very surprising theory: the uncertainty principle seems to say that just knowing something can alter the physical world. Even stranger, entanglement and nonlocality seem to say that knowing something about one object can change another object, even if the other object is light-years away. Fascination with quantum theory has led to thought experiments, and later real experiments, on very strange (but true) possibilities like quantum teleportation.

Many physicists are now asking how we can use these odd quantum effects. In recent years we have discovered ways to use the unique features of quantum mechanics, uncertainty and entanglement, to make new technologies: perfectly secure communications, computers faster than any classical computer, measurements that beat the diffraction limit, and others. Some of these are at the thought experiment stage, some are proof-of-principle experiments, and some are commerical products. All need more work to reach their full potential. This is the task of experimental quantum information.

Here at ICFO we work with some of the best-understood and best-controlled quantum systems, quantum light and cold atoms. This is the area of quantum optics, and it is the main proving-ground for quantum information. One of our major interests is the interaction of quantum light with cold atoms. We use many atoms (an atomic ensemble), and near-resonant light. This creates a strong interaction, and the possibility of technologies that use the best features of both light and atoms.
