Quantum skyrmion parallelism via metasurface-tailored high-dimensional entanglement
Pedro Ornelas, Ramona Bedford, Fazilah Nothlawala +6
Quantum skyrmions are topological structures that have garnered significant interest due to their demonstrated robustness and versatility across diverse optical platforms. However,…
Orthogonalised Self-Guided Quantum Tomography: Insights from Single-Pixel Imaging
Kiki Dekkers, Alice Ruget, Fazilah Nothlawala +6
We introduce the concept of self-guided imaging (SGI) as a linear analogue of self-guided quantum tomography (SGQT). We show that SGI is mathematically equivalent to single-pixel i…
Remote engineering of particle-like topologies to visualise entanglement dynamics
Fazilah Nothlawala, Bereneice Sephton, Pedro Ornelas +6
Skyrmions are a particle-like topology with a quantised skyrmion number, realised across condensed matter and photonic platforms alike. In quantum photonics, they constitute an eme…
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…
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…
