Conditionnal squeezing of an atomic alignement
arXiv:0705.3571 · doi:10.1103/PhysRevA.76.033830
Abstract
We investigate the possibility to perform a Quantum Non Demolition measurement of the collective alignment of an atomic ensemble in the case of a $F\geq 1$ spin. We compare the case of purely vectorial and purely tensorial Hamiltonians and show how to achieve conditional squeezing or entanglement of atomic alignment components.
