Spooky action at a distance not allowed?

Click For Summary
SUMMARY

Sabine Hossenfelder asserts that "spooky action at a distance" is a misconception in quantum mechanics, emphasizing that manipulating one particle in an entangled pair does not instantaneously affect its counterpart unless a measurement is made. She illustrates this by explaining that flipping the spin of one particle without measurement does not alter the state of the other particle. The discussion also highlights the importance of understanding the entangled system as a whole, rather than focusing on individual particles, and critiques the use of vague language in describing quantum phenomena.

PREREQUISITES
  • Understanding of quantum entanglement and measurement principles
  • Familiarity with quantum mechanics terminology, such as "basis state" and "spin flip"
  • Knowledge of quantum computing concepts, particularly quantum gates
  • Basic grasp of hidden variable theories in quantum mechanics
NEXT STEPS
  • Research the implications of quantum entanglement on information theory
  • Study the role of quantum gates in quantum computing
  • Explore Bell's theorem and its significance in hidden variable theories
  • Examine experimental setups for measuring entangled particles, such as polarizers
USEFUL FOR

Quantum physicists, students of quantum mechanics, and anyone interested in the nuances of quantum entanglement and its implications for communication and information theory.

If that is the case then my criticism is that she should have worded it better
You're entitled to your opinion of course. However:

Here is the picture of Stern Gerlach cascade that illustrates what I was trying to explain.
You don't need to keep belaboring this. You're just repeating yourself, and responding would just mean others repeating themselves. Enough is enough.
