Kochen-Specker (KS) sets are key tools for proving some fundamental results in quantum theory and also have potential applications information processing. However, so far, their intrinsic complexity has prevented experimentalists from using them any application. The KS set requiring the smallest number of contexts been recently found. Relying on this simple set, here we report an input state-independent experimental technique to certify whether a measurements is actually accessing...
Nanoscale infrared (IR) resonators with sub-diffraction limited mode volumes and open geometries have emerged as new platforms for implementing cavity quantum electrodynamics at room temperature. The use of IR nanoantennas tip nanoprobes to study strong light-matter coupling molecular vibrations the vacuum field can be exploited control nanometer spatial femtosecond temporal resolution. In order advance development molecule-based nanophotonics in mid-IR, we propose a generally applicable...
Measurement scenarios containing events with relations of exclusivity represented by pentagons, heptagons, nonagons, etc., or their complements are the only ones in which quantum probabilities cannot be described classically. Interestingly, theory predicts that maximum values for any these graphs achieved Bell inequality scenarios. With exception pentagon, this prediction remained experimentally unexplored. Here we test maxima heptagon and complement using three- five-dimensional states,...
Optical nonlinearities are fundamental in several types of optical information processing protocols. However, the high laser intensities needed for implementing phase using conventional materials represent a challenge nonlinear optics few-photon regime. We introduce an infrared cavity quantum electrodynamics (QED) approach imprinting shifts on individual THz pulses reflection setups, conditional input power. Power-dependent order $ 0.1\, \pi$ can be achieved with femtosecond only few $\mu$W...
