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…

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…
