Entanglement from Semiconductor Nanostructures


At the interface between quantum optics and semiconductors we find a rich field of investigation with huge potential for quantum information processing communication technologies. Entanglement is one of the most fascinating concepts in quantum physics research as well as an important resource for quantum information processing.

This project will develop novel sources of entangled photon pairs with semiconductor nanostructures. In particular, we will use the scattering of microcavity exciton-polaritons as an extremely strong optical nonlinearity for the generation of entanglement with properties that are difficult to achieve with the traditional methods. Further we will work with individual semiconductor quantum dots to create controlled single entangled pairs and explore the interfacing of quantum dots to flying qubits.

The long term vision of this research is to create integrated sources of entanglement that can be combined with laser sources, passive optical elements, and even detectors in order to realize the quantum optics lab on a chip.
