Novel photonic topology from two photon driving: applications to quantum information processing
Abstract
Topology is a branch of mathematics concerned with characterizing properties of geometric objects that are robust: these properties do not change if one smoothy deforms the object. Surprisingly, quantum systems can also have topological features: these are properties of the system that cannot be easily changed, even if one adds imperfections or disorder to the system. There is great hope and excitement that one can leverage such quantum topological features to devise robust ways to construct powerful new technologies that directly exploit quantum mechanical behaviour (such as quantum computers or quantum sensors). Most work so far in this direction has focused on quantum systems where electrons are the relevant particles. In contrast, this proposal will advance the study of unusual topological effects that arise in systems where the relevant particles are photons: the particles that make up electromagnetic radiation (including light). We will use these topological effects both to devise new kinds of powerful quantum sensors, and also to generate the kinds of highly correlated entangled quantum states that are the backbone of quantum technologies.
