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…
Topological robustness of orbital angular momentum entanglement in stochastic channels
Tatjana Kleine, Pedro Ornelas, Cade Peters +5
Orbital angular momentum (OAM) entanglement gives access to multiple qubit and high dimensional Hilbert spaces, but is unfortunately susceptible to disturbance, decaying in real-wo…
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…
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…
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…
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…
