5. “I cannot seriously believe in quantum
theory because it cannot be reconciled with
the idea that physics should represent a
reality in time and space, free from
spooky actions at a distance.”
─ Albert Einstein
14. Summary
The entanglement is nonlocal correlation of multiparticle system.
The ghost imaging experiment demonstrates the
entanglement between a pair of photons.
Geometrical optics can apply to quantum optics.
15. “We cannot make the mystery go
away by explaining how it works.
We will just tell you how it works.”
─ Richard P. Feynman
