Low-depth measurement-based deterministic quantum state preparation
Roselyn Nmaju, Fiona Speirits, Sarah Croke
We present a low-depth amplitude encoding method for arbitrary quantum state preparation. Building on the foundation of an existing divide-and-conquer algorithm, we propose a metho…
Stokes and skyrmion tensors and their application to structured light
Stephen M. Barnett, Sonja Franke-Arnold, Fiona C. Speirits
We replace the familiar Stokes vector by a tensor. This allows us to introduce, for example, polar-coordinate components of the Stokes vector. From the tensor we can derive the sky…
Transferability of Photometric Redshifts Determined using Machine Learning
Lara Janiurek, Martin A. Hendry, Fiona C. Speirits
In this work the random forest algorithm GALPRO is implemented to generate photometric redshift posteriors, and its performance when trained and then applied to data from another s…
Theory of paraxial optical Skyrmions
Z. Ye, S. M. Barnett, S. Franke-Arnold +4
Vector light beams, characterised by a spatially varying polarisation, can exhibit localised structures reminiscent of the Skyrmions familiar from the study of magnetic media. We p…
Quantum state preparation of gravitational waves
Fergus Hayes, Sarah Croke, Chris Messenger +1
We detail a quantum circuit capable of efficiently encoding analytical approximations to gravitational wave signal waveforms of compact binary coalescences into the amplitudes of q…
On lines of constant polarisation in structured light beams
Stephen M. Barnett, Fiona C. Speirits, Joerg B. Goette
We show that Skyrmion field lines, constructed from the local Stokes parameters, trace out lines of constant optical polarisation.
