Experimental Tests of Invariant Set Theory
Jonte R. Hance, Tim N. Palmer, John Rarity
We identify points of difference between Invariant Set Theory and standard quantum theory, and show that these lead to noticeable differences in predictions between the two theorie…
Single photon emission and single spin coherence of a nitrogen vacancy centre encapsulated in silicon nitride
Joe A. Smith, Jorge Monroy-Ruz, John G. Rarity +1
Finding the right material platform for engineering efficient photonic interfaces to solid state emitters has been a long-standing bottleneck for scaling up solid state quantum sys…
Deterministic Teleportation and Universal Computation Without Particle Exchange
Hatim Salih, Jonte R. Hance, Will McCutcheon +2
Teleportation is a cornerstone of quantum technologies, and has played a key role in the development of quantum information theory. Pushing the limits of teleportation is therefore…
Is the dynamical quantum Cheshire cat detectable?
Jonte R. Hance, James Ladyman, John Rarity
We explore how one might detect the dynamical quantum Cheshire cat proposed by Aharonov et al. We show that, in practice, we need to bias the initial state by adding/subtracting a…
Methane sensing in the mid-IR using short wave IR photon counting detectors via non-linear interferometry
Arthur C. Cardoso, Jinghan Dong, Haichen Zhou +2
We demonstrate a novel MIR methane sensor shifting measurement wavelength to SWIR (1.55m) by using non-linear interferometry. The technique exploits the interference effects se…
