Modern experimental developments allow to address the fundamental challenges of quantum physics on new, macroscopic scales. How far can such experiments be pushed with current technology? We discuss three specific examples, long‐distance photonic entanglement, matter wave interferometry and superposition states of mechanical resonators, and discuss possible extensions to these experiments. It turns out that there is “plenty of room at the top” for macroscopic quantum experiments, even with presently available technology.
