What is Quantum Optics & Quantum Information?

Quantum Optics deals with the interaction between light and matter on a quantum-mechanical, i.e., single-photon level. Experimental research in this field generally involves a laser and various forms of optical detection, like photon counting or measurement of the optical intensity and/or phase. Our research addresses fundamental issues in this field, where experiment and theory are closely linked and where a thorough knowledge of quantum-mechanics is needed.

Quantum Information is compact jargon for the use of quantum mechanics in information technology. Examples thereof are: quantum communication, quantum cryptography, quantum teleportation and quantum computing. This challenging research field attracts lots of attention and has quickly "conquered terrain" on the more conventional quantum optics. And not without reason. Through the use of mesoscopic multi-particle wavefunctions, which contain a certain form of quantum correlations called quantum entanglement, scientists have already constructed "unbreakable" codes and teleported quantum-mechanical wavefunctions through classical information channels, using clever quantum operations to avoid the dreaded projection postulate. Future challenges in quantum information involve amoung others quantum entanglement in higher dimensions and entanglement betwen distant and macroscopic objects. Quantum optics forms an ideal playground for quantum information, because of the many possibilities to create and control the quantum mechanical wavefunction of one or several photons.
