Experimental demonstration of quantum memory for light
Brian Julsgaard, Jacob Sherson, J. Ignacio Cirac +2
The information carrier of today's communications, a weak pulse of light, is an intrinsically quantum object. As a consequence, complete information about the pulse cannot, even in…
Quantum noise limited interferometric measurement of atomic noise: towards spin squeezing on the Cs clock transition
Daniel Oblak, Jens K. Mikkelsen, Wolfgang Tittel +5
We investigate theoretically and experimentally a nondestructive interferometric measurement of the state population of an ensemble of laser cooled and trapped atoms. This study is…
On separability of quantum states and the violation of Bell-type inequalities
Elena R. Loubenets
In contrast to the wide-spread opinion that any separable quantum state satisfies every classical probabilistic constraint, we present a simple example where a separable quantum st…
"Local Realism", Bell's Theorem and Quantum "Locally Realistic" Inequalities
Elena R. Loubenets
Based on the new general framework for the probabilistic description of experiments, introduced in quant-ph/0305126, quant-ph/0312199, we analyze in mathematical terms the link bet…
