Demonstration of quantum random number generation using nitrogen vacancy centres
Conrad Strydom, Mark Tame
Quantum random number generation (QRNG) relies on the inherent unpredictability of quantum mechanical phenomena to efficiently generate high-quality random numbers that can be used…
Experimental realization of a photonic weighted graph state for quantum metrology
Unathi Skosana, Byron Alexander, Changhyoup Lee +1
Quantum metrology seeks to push the boundaries of measurement precision by harnessing quantum phenomena. Conventional methods often rely on maximally entangled resources, with stat…
Spin-state energetics of heme-related models with the variational quantum eigensolver
Unathi Skosana, Sthembiso Gumede, Mark Tame
We present numerical calculations of the energetic separation between different spin states (singlet, triplet and quintet) for a simplified model of a deoxy-myoglobin protein using…
Stationary two-qubit entanglement mediated by one-dimensional plasmonic nanoarrays
Luke C. Ugwuoke, Tjaart P. J. Krüger, Mark S. Tame
Entanglement is one of the key measures of quantum correlations present in nanophotonic systems, with promising applications in quantum optics and beyond. Previous studies have sho…
Verification of single-photon path entanglement using a nitrogen vacancy center
A. I. Smith, C. M. Steenkamp, M. S. Tame
Path entanglement is an essential resource for photonic quantum information processing, including in quantum computing, quantum communication and quantum sensing. In this work, we…
Quantum plasmonics model of refractive index sensing using photon correlations
L. C. Ugwuoke, T. P. J. Krüger, M. S. Tame
The interaction between the electric dipole moments of a quantum emitter and a metal nanoparticle gives rise to unique optical properties, such as interference-induced photon corre…
