TL;DR: A quantum boson-sampling machine (QBSM) is constructed to sample the output distribution resulting from the nonclassical interference of photons in an integrated photonic circuit, a problem thought to be exponentially hard to solve classically.

TL;DR: In this article, an alternative arrangement of beam splitters and phase shifters was proposed for universal multiport interferometers, which requires half the optical depth of the Reck et al. design and is significantly more robust to optical losses.

TL;DR: In this paper, an alternative arrangement of beam splitters and phase shifters was proposed for universal multiport interferometers, which was shown to be more robust to optical losses.

TL;DR: In this paper, a fully integrated implementation of quantum teleportation in which all key parts of the circuit - entangled state preparation, Bell-state analysis and tomographic state measurement - are performed on a reconfigurable photonic chip is presented.

TL;DR: This work demonstrates three-photon quantum operation of an integrated device containing three coupled interferometers, eight spatial modes and many classical and nonclassical interferences, and introduces a new scheme to verify quantum behaviour, using classically characterised device elements and hierarchies of photon correlation functions.
