Besides the superior efficiency compared to their classical counterparts, quantum algorithms
known so far are basically task-dependent, and scarcely any common features are shared …

This work shows that the majorization of photon distributions is related to the runtime of
classically simulating multimode passive linear optics, which explains one aspect of the …

Entanglement represents a fundamental resource for quantum technologies, including
quantum communication tasks. In this context, photons are the ideal physical systems due to …
