In 2003, with “Playing Pool with π“, G. Galperin invented an extraordinary method to learn the digits of π by counting the collisions of billiard balls. Adam R. Brown at Google has demonstrated an exact isomorphism between Galperin’s
Parametrized quantum optical circuits are a class of quantum circuits in which the carriers of quantum information are photons and the gates are optical transformations. Classically optimizing these circuits is challenging due to the infinite
Discretizing spacetime is often a natural step towards modelling physical systems. For quantum systems, if we also demand a strict bound on the speed of information propagation, we get Quantum Cellular Automata (QCAs). These originally
