Gravitational Decoherence

The field of gravitational quantum physics brings together ideas from quantum information, metrology, and gravitational physics to address questions such as how gravity affects quantum states, whether quantum properties of gravity can be tested in the weak field regime far below the Planck scale, how relativistic concepts extend to quantum systems, and how these effects can be tested experimentally. Many of these questions can now be explored with near-term laboratory experiments and with emerging space-based platforms.
