Quantum Dot Day aims to bring together researchers working on quantum optics, spectroscopy, spin physics, transport, devices and applications, synthesis and growth of semiconductor quantum dots. This workshop will be the latest in a series of highly successful workshops previously held in Lancaster, Sheffield, Edinburgh, Cambridge, Imperial College, Nottingham, QinetiQ, and University College London. It will be an occasion to discuss the latest progress in quantum dot science and technology and to develop collaborations.
