Towards the optimized generation of continuous variables triple-photon states quantum entanglement
Physicists have discovered an unexpected theoretical track to optimize the non-linear generation of triple-photon quantum states. The conclusion: it is better to avoid a blindly taking inspiration from the analoguous and well-controlled process of double-photon quantum states generation.
Phase Stochastic Resonance in a Forced Nanoelectromechanical Membrane
Stochastic resonance is a general phenomenon that can seem paradoxical at first, whereby noise present or injected in a system can enhance the detection of a small signal. It is usually observed in one-dimensional bistable systems subjected to a …

Plasmon fingerprint in Au Nanocrystal assemblies
Hydrophobic Au nanocrystal assemblies (both ordered and amorphous) were dispersed in aqueous solution via the assistance of lipid vesicles. The intertwine between vesicles and Au assemblies was made possible through a careful selection of the length of alkyl chains …

Mapping in real space antiferromagnetic order at nanoscale
Using an artificial atom in diamond as an ultrasensitive magnetic field detector, physicists have for the first time imaged the leakage field radiated by a compound of the vast family of antiferromagnets. This observation allowed them to study the …
