Interests

I am interested in exploring post-quantum theories - those which exhibit phenomena beyond standard quantum mechanics. Such theories offer invaluable insight into how quantum theory manifests and how we might extend it in the future to capture unexplained phenomena.

Of particular interest is furthering our understanding of the transition from a post-quantum theory to quantum theory via a hyper-decoherence process. To this end, I am currently studying the theory of density hypercubes (and similar theories that come from iterating the CPM construction) as a theory which is rich in hyper-decoherence processes and trying to understand how higher-order interference can be used to computational advantage. Interference is the backbone of many quantum algorithms and thus a deeper understanding of its nature may allow us to develop new algorithms while extending our understanding of the physical world.
