Please read the link I gave.
I will be taking my leave of this thread - you need to become acquainted with basic stuff.
Thanks

The link includes words like Linear Algebra in Dirac Notation. How do you expect us who know only how to add, subtract, multiply divide to comprehend them.
Hope others would give other easier reference with mostly verbal summaries..
Anyway. I think I understood the difference between superposition with and without entanglement.
Here's the summary:
1. Entanglement only works for subatomic particles in pure state, you can't entangle system already in mixed states.
2. Superposition is when the entanglement for instance takes all positions (say in position observable) .
3. The EPR pair can't be in entanglement with the apparatus because the apparatus is in mixed state.. which destroyed the EPR pair in pure state.
If the above are all correct. Then I understood it and end of thread. Hope someone can verify what I learned so far from the exchanges with Mr. Hobba. Thanks to him I grasped more.
