SUMMARY:Levitating nanodiamond experiments: towards a test of quantum grav

DESCRIPTION:We are building an experiment in which a nitrogen-vacancy-cent
 re electron spin would be used to put a levitated nanodiamond into a spati
 al quantum superposition [1\,2]. This would be able to test theories of sp
 ontaneous wavefunction collapse and is the first step of a much more ambit
 ious experiment to test if gravitational effects can be in a quantum super
 position [3\,4]. This seminar will describe our improved experimental desi
 gn [1\,5-7] and early experimental progress [5\,8\,9].\n\n[1] M. Scala\, M
