Contrast inverted ghost imaging with non-interacting photons
Nicholas Bornman, Megan Agnew, Feng Zhu +3
Ghost imaging is the remarkable process where an image can be formed from photons that have not "seen" the object. Traditionally this phenomenon has required initially correlated b…
Simultaneous entanglement swapping of multiple orbital angular momentum states of light
Yingwen Zhang, Megan Agnew, Thomas Roger +5
Entanglement swapping generates remote quantum correlations between particles that have not interacted and is the cornerstone of long-distance quantum communication, quantum networ…
Reconstructing high-dimensional two-photon entangled states via compressive sensing
Francesco Tonolini, Susan Chan, Megan Agnew +2
Accurately establishing the state of large-scale quantum systems is an important tool in quantum information science; however, the large number of unknown parameters hinders the ra…
Inferring causal structure: a quantum advantage
Katja Ried, Megan Agnew, Lydia Vermeyden +3
The problem of using observed correlations to infer causal relations is relevant to a wide variety of scientific disciplines. Yet given correlations between just two classical vari…
Discriminating single-photon states unambiguously in high dimensions
Megan Agnew, Eliot Bolduc, Kevin J. Resch +2
The ability to uniquely identify a quantum state is integral to quantum science, but for non-orthogonal states, quantum mechanics precludes deterministic, error-free discrimination…
Coherent ultrafast measurement of time-bin encoded photons
John M. Donohue, Megan Agnew, Jonathan Lavoie +1
Time-bin encoding is a robust form of optical quantum information, especially for transmission in optical fibers. To read out the information, the separation of the time bins must…
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…
Entangled Bessel beams
Melanie McLaren, Megan Agnew, Jonathan Leach +3
Orbital angular momentum (OAM) entanglement is investigated in the Bessel-Gauss (BG) basis. Having a readily adjustable radial scale, BG modes provide a more favourable basis for O…
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…
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…
