Neural networks detect nonclassicality

A properly-trained artificial neural network is able to correctly identify classical and nonclassical features from real experimental data for different states of light. See more in Physical Review Research.

New tests of nonclassical behavior

We experimentally test new ways to detect the nonclassicality of a state from correlations among different phase-space distributions. See our latest PRL paper.

“Share one to entangle them all”

The delocalized addition of a single photon entangles two separate laser pulses containing an average of up to 60 photons each. Our recent results have just appeared in a paper on PRL.

Generating nonclassical states from hybrid systems

How to generate a nonclassical continuous-variable (CV) state by making measurements on the discrete-variable (DV) part of a compound CV-DV system? Find out in our latest PRL paper.

Optical Kerr effect with less than one photon

We emulated the self-phase modulation typical of strong optical Kerr nonlinearity on coherent light pulses containing less than a single photon (on average). These results just appeared in PRL.
