Entangled states Einstein-Podolsky-Rosen paradox

It turned out that in the Bohr-Einstein controversy, Bohr was right. The Einstein-Podolsky-Rosen paradox resulted (in agreement with Bohr s view) in the concept of entangled states. These states have been used experimentally teleport a photon state without violating the Heisenberg uncertainty principle. Also, the entangled states stand behind the idea of quantum computing with a superposition (qubit) of two states a 0) + b l) instead of 0) and 1) as information states. 

Abstract We consider a possible realization of the position- and momentum-correlated atomic pairs that are confined to adjacent sites of two mutually shifted optical lattices and are entangled via laser-induced dipole-dipole interactions. The Einstein-Podolsky-Rosen (EPR) "paradox" [Einstein 1935] with translational variables is then modified by lattice-diffraction effects. We study a possible mechanism of creating such diatom entangled states by varying the effective mass of the atoms. 

Einstein, Podolsky and Rosen (EPR) [Einstein 1935] asked the question of whether the quantum mechanical description of physical world is complete, giving the following example. Two-particles are in the quantum state showing strange correlations if one measures the position or momentum of one particle, one can predict with certainty the result of measuring their counterpart for the second particle. Thus, depending on which measurement is chosen for the first particle, the value of either the momentum or position can be predicted with arbitrary precision for the other particle. The later discussion has concerned the interpretation of the EPR paradox and its implications on quantum theory [Bohr 1935], Later, Bohm considered [Bohm 1951] two entangled spin-1/2 particles, which have become the center of attention on this EPR issue their...
