Quantum-secured imaging
Mehul Malik, Omar S. Magaña-Loaiza, Robert W. Boyd
We have built an imaging system that uses a photon's position or time-of-flight information to image an object, while using the photon's polarization for security. This ability all…
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…
Entanglement verification via nonlinear witnesses
Megan Agnew, Jeff Z. Salvail, Jonathan Leach +1
The controlled generation of entangled states and their subsequent detection are integral aspects of quantum information science. In this work, we analyse the application of nonlin…
Measurement of the Orbital Angular Momentum Spectrum of Partially Coherent Fields using Double Angular Slit Interference
Mehul Malik, Sangeeta Murugkar, Jonathan Leach +1
We implement an interferometric method using two angular slits to measure the orbital angular momentum (OAM) mode spectrum of a partially coherent field. As the angular separation…
Near-Perfect Sorting of Orbital Angular Momentum and Angular Position States of Light
Malcolm N. O'Sullivan, Mohammad Mirhosseini, Mehul Malik +1
We present a novel method for efficient sorting of photons prepared in states of orbital angular momentum (OAM) and angular position (ANG). A log-polar optical transform is used in…
Full characterisation of polarisation states of light via direct measurement
Jeff Z. Salvail, Megan Agnew, Allan S. Johnson +3
Ascertaining the physical state of a system is vital in order to understand and predict its behaviour. Tomography is a standard approach used to determine the form of an unknown st…
