Linear-optical circuits may become important elementary building blocks of quantum computers in the future. Especially integrated photonics has the prospect of being scaleable by using technology from chip manufacturing. Here, we present an efficient, robust, and conceptually simple technique for characterising such a chip based on recent advances in low-rank matrix recovery. We also report on a successful experimental implementation using a universal six-mode linear optics chip.
