Heterodyne non-demolition measurements on cold atomic samples: towards the preparation of non-classical states for atom interferometry
Simon Bernon, Thomas Vanderbruggen, Ralf Kohlhaas +3
We report on a novel experiment to generate non-classical atomic states via quantum non-demolition (QND) measurements on cold atomic samples prepared in a high finesse ring cavity.…

Spin-squeezing and Dicke state preparation by heterodyne measurement
Thomas Vanderbruggen, Simon Bernon, Andréa Bertoldi +2
We investigate the quantum non-demolition (QND) measurement of an atomic population based on a heterodyne detection and show that the induced back-action allows to prepare both spi…
