Building Quantum GR out of quantum rulers and quantum clocks

In summary, Quantum GR is a theoretical framework that combines quantum mechanics and general relativity to explain the behavior of the universe on both small and large scales. Quantum rulers and clocks are crucial in building this theory, as they allow for the study of gravity on a quantum level. The concept of quantum entanglement is also relevant to Quantum GR, as it may help explain how gravity arises from the quantum structure of space-time. However, there are challenges in reconciling the principles of quantum mechanics and general relativity, as well as developing the technology to build quantum rulers and clocks. While we are still in the early stages of understanding Quantum GR, advancements in technology and continued research could lead to a more complete understanding of the universe and potentially groundbreaking discoveries

Hi, has anyone tried to build "quantum GR", using the expectation value of |Psi(x)> as a "quantum ruler" and |Psi(t)> as a "quantum clock" to build up the idea of a "quantum metric"?

What is |Psi(t)>? How do you calculate it? Can you show an example?
