Abstract:
Gravity and quantum physics are usually relevant at vastly different scales. But the advent of quantum information science and the control over novel quantum systems has opened new opportunities for studying phenomena at the interface of general relativity and quantum mechanics. In this talk I will discuss some of these developments, with examples from my own research that relate to opto-mechanical systems, atomic clocks and matter-wave interferometry. I will present quantum interferometry with superpositions of proper time, which opens the route to probe quantum theory on curved spacetime in near future experiments. I will also present some examples of testing quantum gravity phenomenology using tools and concepts from quantum information processing, as well as their current limitations. The presented results will show near-future opportunities to study the interplay of general relativity and quantum theory in quantum optical experiments.
