Sub-Poissonian atom number fluctuations using light-assisted collisions
Y. R. P. Sortais, A. Fuhrmanek, R. Bourgain +1
We investigate experimentally the number statistics of a mesoscopic ensemble of cold atoms in a microscopic dipole trap loaded from a magneto-optical trap, and find that the atom n…
Cold and trapped metastable noble gases
Wim Null Vassen, Claude Cohen-Tannoudji, Michèle Leduc +7
We review experimental and theoretical work on cold, trapped metastable noble gases. We em- phasize the aspects which distinguish work with these atoms from the large body of work…
Useful Multiparticle Entanglement and Sub-Shot-Noise Sensitivity in Experimental Phase Estimation
Roland Krischek, Christian Schwemmer, Witlef Wieczorek +4
We experimentally demonstrate a general criterion to identify entangled states useful for the estimation of an unknown phase shift with a sensitivity higher than the shot-noise lim…
Estimation of a quantum interaction parameter using weak measurements: Theory and experiment
Holger F. Hofmann, Michael E. Goggin, Marcelo P. Almeida +1
We investigate the estimation of a small interaction parameter from the outcomes of weak quantum measurements implemented by the interaction. The relation of weak values and sensit…
Electromagnetic Energy, Absorption, and Casimir Forces. Inhomogeneous Dielectric Media
F. S. S. Rosa, D. A. R. Dalvit, P. W. Milonni
A general, exact formula is derived for the expectation value of the electromagnetic energy density of an inhomogeneous absorbing and dispersive dielectric medium in thermal equili…
A method for characterizing coherent-state quantum gates
Rémi Blandino, Franck Ferreyrol, Marco Barbieri +2
We discuss and implement experimentally a method for characterizing quantum gates operating on superpositions of coherent states. The peculiarity of this encoding of qubits is to w…
