Comparing the wavefunction of single and entangled particle

Click For Summary
SUMMARY

The discussion centers on the interaction of wavefunctions of single and entangled particles, specifically addressing how a particle's wavefunction is influenced by the presence of another particle. It is established that the wavefunction belongs to the entire system rather than individual particles, and that entanglement arises from interactions between particles. The Hamiltonian governs the dynamics of the system, and the concept of path integrals is crucial for understanding particle behavior in quantum mechanics. The participants also explore the implications of entanglement and measurement, emphasizing that entangled states cannot be described independently.

Your reasoning escapes me.

The ignorance ensemble applies to QM and QFT. Quantum gravity, as the link I gave explains, is a perfectly good theory up to a cut-off. What's beyond the cut-off - who knows. It may necessitate a revision of the other stuff - but as of now there is no issue.

QM and QFT are just effective field theory.. their spacetime are fixed. In general relativistic quantum field theory, the fields interacts with geometry. So before wavefunction collapse or even EPR particle entanglements, won't the geometry be able to track the fields or particles while still in pure states?

Don't know that one - have you a paper?

And if you don't can we stick to conventional physics?

Thanks
