Characterization of high-dimensional entangled systems via mutually unbiased measurements
D. Giovannini, J. Romero, J. Leach +3
Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science, such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional systems…
EPR-based ghost imaging using a single-photon-sensitive camera
Reuben S. Aspden, Daniel S. Tasca, Robert W. Boyd +1
Correlated-photon imaging, popularly known as ghost imaging, is a technique whereby an image is formed from light that has never interacted with the object. In ghost imaging experi…
Influence of Atmospheric Turbulence on Optical Communications using Orbital Angular Momentum for Encoding
Mehul Malik, Malcolm O'Sullivan, Brandon Rodenburg +5
We describe an experimental implementation of a free-space 11-dimensional communication system using orbital angular momentum (OAM) modes. This system has a maximum measured OAM ch…
Imaging high-dimensional spatial entanglement with a camera
Matthew P. Edgar, Daniel S. Tasca, Frauke Izdebski +6
The light produced by parametric down-conversion shows strong spatial entanglement that leads to violations of EPR criteria for separability. Historically, such studies have been p…
