Dear Dr. B: What is the difference between entanglement and superposition?



The only photo in existencethat shows me in high heels.

This is an excellent question which you didn�t ask. I�ll answer it anyway because confusing entangled states with superpositions is a very common mistake. And an unfortunate one: without knowing the difference between entanglement and superposition the most interesting phenomena of quantum mechanics remain impossible to understand � so
