TL;DR: A programmable photonic integrated circuit as mentioned in this paper implements arbitrary linear optics transformations in the spatial mode basis with high fidelity under a realistic fabrication model, and it is shown that programmability dramatically improves device tolerance to fabrication imperfections and enables a single device to implement a broad range of both quantum and classical linear optics experiments.

TL;DR: A high-dimensional quantum key distribution protocol secure against collective attacks is implemented and transform between conjugate measurement bases using group velocity dispersion.

TL;DR: In this paper, a reconfigurable silicon quantum photonic network for implementing general linear optics transformations in the spatial mode basis is introduced, which enables implementation of a range of quantum algorithms.
