Efficient quantification of non-Gaussian spin distributions
B. Dubost, M. Koschorreck, M. Napolitano +3
We study theoretically and experimentally the quantification of non-Gaussian distributions via non-destructive measurements. Using the theory of cumulants, their unbiased estimator…
Comment on "Superradiant Phase Transitions and the Standard Description of Circuit QED"
Cristiano Ciuti, Pierre Nataf
A Comment on the Letter by O. Viehmann, J. von Delft, and F. Marquardt [Phys. Rev. Lett. {\bf 107}, 113602 (2011)].
Quantum correlations by four-wave mixing in an atomic vapor in a non-amplifying regime: a quantum beam splitter for photons
Quentin Glorieux, Luca Guidoni, Samuel Guibal +2
We study the generation of intensity quantum correlations using four-wave mixing in a rubidium vapor. The absence of cavity in these experiments allows to deal with several spatial…
Cavity QED of the graphene cyclotron transition
David Hagenmüller, Cristiano Ciuti
We investigate theoretically the cavity quantum electrodynamics of the cyclotron transition for Dirac fermions in graphene. We show that the ultrastrong coupling regime characteriz…
Double symmetry breaking and 2D quantum phase diagram in spin-boson systems
Pierre Nataf, Alexandre Baksic, Cristiano Ciuti
The quantum ground state properties of two independent chains of spins (two-levels systems) interacting with the same bosonic field are theoretically investigated. Each chain is co…
Magnetic sensitivity beyond the projection noise limit by spin squeezing
R. J. Sewell, M. Koschorreck, M. Napolitano +3
We report the generation of spin squeezing and entanglement in a magnetically-sensitive atomic ensemble, and entanglement-enhanced field measurements with this system. A maximal Ra…
