Quantum Optical State Comparison Amplifier
Electra Eleftheriadou, Stephen M. Barnett, John Jeffers
It is a fundamental principle of quantum theory that an unknown state cannot be copied or, as a consequence, an unknown optical signal cannot be amplified deterministically and per…
Mutually unbiased measurements for high-dimensional time-bin based photonic states
Thomas Brougham, Stephen M. Barnett
The task of measuring in two mutually unbiased bases is central to many quantum information protocols, as well as being of fundamental interest. Increasingly, there is an experimen…
Beyond Landauer erasure
Stephen M. Barnett, Joan A. Vaccaro
In thermodynamics one considers thermal systems and the maximization of entropy subject to the conservation of energy. A consequence is Landauer's erasure principle, which states t…
Enhancing the sensitivity of the LIGO gravitational wave detector by using squeezed states of light
The LIGO Scientific Collaboration
Nearly a century after Einstein first predicted the existence of gravitational waves, a global network of earth-based gravitational wave observatories is seeking to directly detect…
Stability of point spectrum for three-state quantum walks on a line
M. Stefanak, I. Bezdekova, I. Jex +1
Evolution operators of certain quantum walks possess, apart from the continuous part, also point spectrum. The existence of eigenvalues and the corresponding stationary states lead…
Tailored two-photon correlation and fair-sampling: a cautionary tale
Jacquiline Romero, Daniel Giovannini, Daniel Tasca +2
We demonstrate an experimental test of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality which seemingly exhibits correlations beyond the limits imposed by quantum mechanics. I…
Investigations of afterpulsing and detection efficiency recovery in superconducting nanowire single-photon detectors
Viacheslav Burenkov, He Xu, Bing Qi +2
We report on the observation of a non-uniform dark count rate in Superconducting Nanowire Single Photon Detectors (SNSPDs), specifically focusing on an afterpulsing effect present…
Two-photon optics of Bessel-Gaussian modes
Melanie McLaren, Jacquiline Romero, Miles J. Padgett +2
In this paper we consider geometrical two-photon optics of Bessel-Gaussian modes generated in spontaneous parametric down-conversion of a Gaussian pump beam. We provide a general t…
Direct Measurement of a 27-Dimensional Orbital-Angular-Momentum State Vector
Mehul Malik, Mohammad Mirhosseini, Martin P. J. Lavery +3
The measurement of a quantum state poses a unique challenge for experimentalists. Recently, the technique of "direct measurement" was proposed for characterizing a quantum state in…
Optimising the use of detector arrays for measuring intensity correlations of photon pairs
Daniel S. Tasca, Matthew P. Edgar, Frauke Izdebski +2
Intensity correlation measurements form the basis of many experiments based on spontaneous parametric down-conversion. In the most common situation, two single-photon avalanche dio…
On-chip quantum interference between silicon photon-pair sources
Joshua W. Silverstone, Damien Bonneau, Kazuya Ohira +12
Large-scale integrated quantum photonic technologies will require the on-chip integration of identical photon sources with reconfigurable waveguide circuits. Relatively complex qua…
