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.

Quantum tomography of homodyne detectors
We suggest and experimentally demonstrate a tomographic method to characterize homodyne detectors at the quantum level. Our results have just appeared in New Journal of Physics.

Limits to XUV frequency combs?
By measuring the tiny phase fluctuations between consecutive pulses from an infrared laser frequency comb we pose stringent limits to the extension of its spectroscopic and metrological applications towards the extreme ultraviolet. Just appeared in PRL.
