We argue that the (linearized) gravitational field of a massive object in a quantum superposition has to exhibit genuine quantum features. More...


In this work, we show near field detection of the motion of a 150 nm silica particle (2 fg, 1e10 a.m.u.) levitated in an optical tweezer.


In this work we demonstrate the violation of a Bell inequality involving a massive, macroscopic mechanical system.
