Fiber optical implementation of the Deutsch-Josza algorithm

A robust method for manipulating multidimensional quantum information encoded in time bins in optical fibers is demonstrated. This is illustrated by implementing the Deutsch-Josza algorithm, but this also applies to the Bemstein-Vazirani algorithm and, with slight modifications, to other quantum computation problems (such as the distributed Deutsch-Josza problem) and to multidimensional quantum cryptography.
