Topic: photons

Mete Atatüre examines semiconductor quantum dots as interfaces between photons, electron spins and ensembles of nuclear spins. Optical control can turn the nuclear environment from a source of noise into a useful quantum system. The seminar follows this progression through collective nuclear states toward a register capable of storing quantum information.

Pascale Senellart traces the development of technologies that directly exploit superposition and entanglement. Experimental control of photons, atoms and fabricated quantum systems has enabled new ways to encode and process information. The lecture connects these advances to quantum computation, secure communication and sensitive measurements, while explaining the close relationship between fundamental research and technological development.
