Building Quantum GR out of quantum rulers and quantum clocks

Click For Summary
SUMMARY

The discussion focuses on the concept of building "quantum general relativity" (GR) using quantum rulers and quantum clocks, specifically utilizing the expectation value of the wave function |Psi(x)> as a quantum ruler and |Psi(t)> as a quantum clock. Participants inquire about the calculation of |Psi(t)> and seek examples to illustrate its application in developing a quantum metric. The conversation emphasizes the theoretical framework and mathematical foundations necessary for this advanced topic in quantum physics.

PREREQUISITES
  • Understanding of quantum mechanics and wave functions
  • Familiarity with general relativity concepts
  • Knowledge of quantum measurement theory
  • Basic proficiency in mathematical physics
NEXT STEPS
  • Research the mathematical formulation of quantum metrics in quantum GR
  • Explore the role of expectation values in quantum mechanics
  • Study the implications of quantum clocks and rulers in theoretical physics
  • Investigate existing models of quantum general relativity
USEFUL FOR

The discussion is beneficial for theoretical physicists, quantum mechanics researchers, and students interested in the intersection of quantum theory and general relativity.

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?
