“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.
