"resolving arrival times overcome using Hong-Ou-Mandel interference quantum effect... time-bin quantum encoding, storing information in time at which photons arrive... combined with quantum walk technique describing single photon movement over different paths in time, enabling use with high-dimensional qudits greatly increasing amount of information processed/ transmitted, and making communications more secure... >99% fidelity... generates quantum entanglement between different properties of single photons"
