Zusammenfassung

Quantum experiments are being conducted with larger and larger systems of higher and higher masses. Gravitational effects could soon become relevant in these experiments. This creates the opportunity for an experimental evaluation of our concepts of space, time, and matter, and can pave the way to the yet unknown theory uniting general relativity and quantum mechanics. If we ask how a quantum superposition state sources the gravitational field, there are two possible answers: the gravitational field itself being in a superposition or the geometrical concept of classical space-time remaining va...
