The Physics of Ghost imaging

What is so special about entangled two-photon state?“Can quantum mechanical physical reality beconsidered complete?”Einstein, Poldosky, Rosen, Phys. Rev. 47, 777 (1935).Proposed the entangled two-particle wavefunction accordingto the principle of quantum superposition:x 1, x 2 dp p x 2 u p x 1 (x 1 x 2 x 0)p 1, p 2 dx x p 2 v x p 1 (p 1 p 2)Non-factorizablewavefunctionAgainstx1,x21x22x1p, p ( p ) ( p )121122Factorizablewavefunction
