"From Macroscopic Superpositions to Quantum Gravity"
We will start by justifying the importance of creating ever more macroscopic quantum superpostions and the great progress already made in this arena (much of which have been made in Vienna). I will then highlight the convenience of a method were a bonafide ancillary quantum system is coupled to a much more macroscopic system to achieve the above. In particular, I will describe how Ramsey interferometry on a spin degree of freedom can be used to create and verify such a superposition and how the scale can be enhanced by using freely propagating (untrapped) objects. Finally, we will show how two such interferometers interacting purely gravitationally can enable one to test whether gravity is fundamentally a"quantum" entity.
