Not all pure entangled states are useful for sub shot-noise interferometry

Philipp Hyllus, Otfried Gühne, Augusto Smerzi

We investigate the connection between the shot-noise limit in linear interferometers and particle entanglement. In particular, we ask whether or not sub shot-noise sensitivity can…

Excitation mapping of whispering gallery modes in silica microcavities

Guoping Lin, Bo Qian, Fedja Orucevic +5

We report the direct observation of the electromagnetic-field distribution of whispering?gallery modes in silica microcavities (spheres and toroids). It is revealed by their excita…

Collective decoherence of cold atoms coupled to a Bose-Einstein condensate

M. A. Cirone, G. De Chiara, G. M. Palma +1

We examine the time evolution of cold atoms (impurities) interacting with an environment consisting of a degenerate bosonic quantum gas. The impurity atoms differ from the environm…

Rabi Interferometry and Sensitive Measurement of the Casimir-Polder Force with Ultra-Cold Gases

Jan Chwedeńczuk, Luca Pezzé, Francesco Piazza +1

We show that Rabi oscillations of a degenerate fermionic or bosonic gas trapped in a double-well potential can be exploited for the interferometric measurement of external forces a…

Estimating multipartite entanglement measures

A. Osterloh, P. Hyllus

We investigate the lower bound obtained from experimental data of a quantum state , as proposed independently by Gühne et al. and Eisert et al. for mixed states of three qubits.…

Photon Wave-packet Manipulation via Dynamic Electromagnetically Induced Transparency in Multilayer Structures

Francesco Bariani, Iacopo Carusotto

We present a Maxwell-Bloch description of the dynamics of a light pulse propagating through a spatially inhomogeneous system consisting of alternating layers of EIT media and vacuu…

Extracavity quantum vacuum radiation from a single qubit

Simone De Liberato, Dario Gerace, Iacopo Carusotto +1

We present a theory of the quantum vacuum radiation that is generated by a fast modulation of the vacuum Rabi frequency of a single two-level system strongly coupled to a single ca…

Light scattering by ultracold atoms in an optical lattice

Stefan Rist, Chiara Menotti, Giovanna Morigi

We investigate theoretically light scattering of photons by ultracold atoms in an optical lattice in the linear regime. A full quantum theory for the atom-photon interactions is de…
