* Idea: Gravitational decoherence is the loss of coherence in low-energy quantum systems resulting from random metric fluctuations.
* Proposals: (Kay) Based on a unitary framework for quantum gravity, assumes that the operators tied to the gravitational degrees of freedom are unobservable and equates physical entropy with matter-gravity entanglement entropy; (Blencowe) Weak gravitational waves that fill the Universe are enough to disturb quantum superpositions and ensure that large objects behave according to classical physics.
