Tunable spatio-spectral Target Skyrmions and topological multiplexing
Pedro Ornelas, Niladri Modak, Oussama Korichi +3
Optical Skyrmions have recently garnered much interest providing a potential avenue for high capacity, robust topological information transfer. Typically, Skyrmions are derived fro…
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…
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…
Reconfigurable circuit for mode tunable topological quantum structured light
Pedro Ornelas, Tatjana Kleine, André G. de Oliveira +3
Structured light in the quantum regime has garnered considerable attention due to the opportunities it offers when mixing light's internal degrees of freedom, for high-dimensional…
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…
