QUROPE Quantum Information Processing and Communication in Europe

One can regard quantum entanglement as the fundamental resource needed in order to execute quantum algorithms. Certain kinds of entangled states exist which are universal resources, in the sense that any quantum algorithm can be performed simply by performing a prescribed series of quantum measurements. Moreover, even the entangled state itself can by created by making measurements [1]. These insights have led to many new possible implementations of quantum computers, for example: one that uses only photons, one exploiting crossed atomic beams and others based on optical measurements on colour centres in diamond.

In this project, you will develop enabling theory that will allow the creation of entangled electronic states of remote nanostructures such as quantum dots, molecules, or crystal defects. Our aim is devise robust protocols that rely simply on the observation of emitted photons from the nanostructures following optical excitation. There will be opportunities for collaboration with experimentalists and theorists both locally in Scotland, at the University of Oxford, Imperial College London and the National University of Singapore.
