Deep diffractive optical neural networks for detecting Skyrmionic topologies of light
Hadrian Bezuidenhout, Cade Peters, Ram Kumar +2
Optical Skyrmions are topological forms of structured light with the potential of an infinite encoding alphabet that is immune to disturbance. This attractive prospect is hindered…
Towards reconstructing quantum structured light on a quantum computer
Mwezi Koni, Shawal Kassim, Paola C. Obando +2
We introduce a variational quantum computing approach for quantum state reconstruction within a discretized logical framework, using experimental measurement data as input. By mapp…
Unveiling the link between quantum ghost imaging and Grover's quantum searching algorithm
Neelan Gounden, Fazilah Nothlawala, Paola C. Obando +3
Photonic quantum technologies have become pivotal in the implementation of communication, imaging and computing modalities. Among these applications, quantum ghost imaging (GI) exp…
Orbital angular momentum of entangled photons as a probe for relativistic effects
Fazilah Nothlawala, Kiki Dekkers, Moslem Mahdavifar +3
Orbital angular momentum (OAM) as both classical and quantum states of light has proven essential in numerous applications, from high-capacity information transfer to enhanced prec…
On-chip photon entanglement-assisted topology loading and transfer
Haoqi Zhao, Yichi Zhang, Isaac Nape +6
Topological protection offers a robust solution to the challenges of noise and loss in physical systems. By integrating topological physics into optics, loading and encoding quantu…
Dual-wavelength quantum skyrmions from liquid crystal topological defect
Mwezi Koni, Fazilah Nothlawala, Vagharshak Hakobyan +3
We propose a spin-orbit strategy for generating dual-wavelength quantum skyrmions, realized either as entangled photon pairs at dual wavelengths or as heralded single-photon states…
Wavelength-adaptive spin-orbit orbital angular momentum management in three-wave mixing
Kiki Dekkers, Mwezi Koni, Vagharshak Hakobyan +5
Here we propose the use of an adjustable liquid crystal spin-orbit device to shape bi-colour structured light to create bimodal states. We demonstrate the proof-of-principle for tw…
The topological spectrum of high dimensional quantum states
Robert de Mello Koch, Pedro Ornelas, Neelan Gounden +3
Topology has emerged as a fundamental property of many systems, manifesting in cosmology, condensed matter, high-energy physics and waves. Despite the rich textures, the topology h…
Enhanced fidelity in nonlinear structured light by virtual light-based apertures
Sachleen Singh, Isaac Nape, Andrew Forbes
Tailoring the degrees of freedom (DoF) of light for a desired purpose, so-called structured light, has delivered numerous advances over the past decade, ranging from communications…
Tailoring light to create invariant modal spectra through complex channels
Cade Peters, Isaac Nape, Andrew Forbes
Light's spatial degree of freedom is emerging as a potential resource for a myriad of applications, in both classical and quantum domains, including secure communication, sensing a…
