Abstract :
In this paper, standard quantum limits for center-of-mass fluctuations of fermionic and bosonic quantum gases is obtained, as well as a novel, second-order measure of condensate formation. It is also shown how these measures relate to standard techniques for preparing and propagating these systems, via exact first principles many-body quantum simulations without factorization approximations.
