Quantum non-demolition measurements using Bose-Einstein condensates
S Choi, K Burnett
Abstract
We study possible scenarios for quantum non-demolition measurements using Bose-Einstein condensates. We show that the interactions between condensate atoms make it possible to measure the atom number with minimal back-action on the system. This is an example of atomic nonlinear optics that has significant implications in the quantum state preparation of the Bose condensates.
