Abstract

One of the biggest unsolved problems in fundamental physics is the unification of quantum mechanics and gravity. One of the consequences of unification could be the existence of "incoherent conformal waves" in gravitational fields due to quantum mechanical zero-point fluctuations. Recent theories have demonstrated that these fluctuations change the first order correlation function of matterwaves. A spacecraft mission called Hyper is being designed to conduct matterwave experiments in space. An order of magnitude improvement may be gained by going into orbit reducing the effects of environmental interactions. Such experiments could put constraints on the upper bands of measurements of decoherence of a matterwave interferometer due to quantum fluctuations.
