Boson Sampling on a Photonic Chip
Justin B. Spring,Benjamin J. Metcalf,Peter C. Humphreys,W. Steven Kolthammer,Xian-Min Jin,Xian-Min Jin,Marco Barbieri,Aanimesh Datta,Nicholas Thomas-Peter,Nathan K. Langford,Nathan K. Langford,Dmytro Kundys,James C. Gates,Brian J. Smith,Pete Smith,Ian A. Walmsley +15 more
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.
Journal ArticleDOI
Optimal design for universal multiport interferometers
William R. Clements,Peter C. Humphreys,Benjamin J. Metcalf,W. Steven Kolthammer,Ian A. Walmsley +4 more
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, 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.

Multiphoton quantum interference in a multiport integrated photonic device
Benjamin J. Metcalf,Nicholas Thomas-Peter,Justin B. Spring,Dmytro Kundys,Matthew A. Broome,Peter C. Humphreys,Xian-Min Jin,Xian-Min Jin,Marco Barbieri,W. Steven Kolthammer,James C. Gates,Brian J. Smith,Nathan K. Langford,Pete Smith,Ian A. Walmsley +14 more
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.
