Solid-state spin-photon interfaces for quantum information processing
Time: 3:30 pm - 5:00 pm
Place: Discovery Building, DeLuca Forum
Speaker: Peter Lodahl, Niels Bohr Institute, University of Copenhagen
Abstract:

Semiconductor quantum dots embedded in photonic nanostructures offer a highly efficient and coherent deterministic photon-emitter interface enabling on-demand single-photon sources and multi-photon entanglement sources. We discuss the fundamental operational principles of these devices and introduce a protocol of deterministic entanglement generation by controlling a single spin in the quantum dot. We will present the experimental state-of-the-art of multi-photon entanglement generation including the realization of photon fusion, which is a primitive for fusion-based quantum computing. Finally, we discuss potential applications of this novel hardware for quantum communication and photonic quantum computing.

This event starts at 3:30pm with refreshments. The invited presentation starts at 4pm.
