"Decoherence usually requires interaction with something macroscopic and an environment"

SUMMARY

Decoherence requires interaction with macroscopic environments, as stated by Bhobba. The discussion explores the implications of freezing an object to eliminate thermal vibrations and cosmic microwave background radiation (CMBR) exposure, questioning whether decoherence would cease for the object's atoms and molecules. The collapse interpretation suggests that without decoherence, these particles would exist as vectors in Hilbert space, potentially becoming invisible. The conversation highlights misconceptions surrounding this topic, emphasizing the need for clarity in future discussions.

PREREQUISITES
  • Understanding of quantum decoherence
  • Familiarity with Hilbert space concepts
  • Knowledge of thermal vibrations and their effects on quantum systems
  • Awareness of cosmic microwave background radiation (CMBR)
NEXT STEPS

Bhobba said "Decoherence usually requires interaction with something macroscopic and an environment".

I assume decoherence still occur to the atoms and molecules inside any object because they are exposed to the thermal vibrations and CMBR.

Let's say for sake of discussion we can freeze an object such that the thermal vibrations no longer serve as environment and put it in container that would completely avoid any CMBR exposure. So decoherence won't happen to the atoms/molecules?

Using collapse interpretation.. without decoherence.. they won't collapse.. so does it mean the atoms/molecules and object suddenly become vectors in Hilbert space and vanish from physical sight? To what extend has experiments like this been done?

This was a misconception when you brought it up in a previous thread and it's still a misconception. Please do not post about it again.
