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…
