Entangling macroscopic diamonds at room temperature: bounds on the CSL parameters
Year: 2016
Type: preprint
Abstract: A recent experiment announced on Science [1] succeeded in detecting entanglement between two macroscopic specks of diamonds, separated by a macroscopic distance, at room temperature. This impressive results is a further confirmation of the validity of quantum theory in (at least parts of) the mesoscopic and macroscopic domain, and poses a challenge to collpase models, which predict a violation of the quantum superposition principle, which is the bigger the larger the system. We analyze the experiment in the light of such models. We will show that the bounds placed by experimental data are weaker than those coming from mater-wave interferometry and non-interferometric tests of collapse models.
