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.

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.
Journal ArticleDOI
Deterministic delivery of remote entanglement on a quantum network.

TL;DR: In this article, a single-photon entanglement protocol was proposed to achieve entangling fidelity of more than 0.5 at every clock cycle of about 100 milliseconds without any pre- or post-selection.

An 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 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.
Journal ArticleDOI
Quantum enhanced multiple phase estimation.
TL;DR: This work identifies quantum probe states that provide an enhancement compared to the best quantum scheme for the estimation of each individual phase separately as well as improvements over classical strategies that provides an advantage in the variance of the estimation over individual quantum estimation schemes that scales as O(d), where d is the number of phases.
