ABSTRACT  |  Abstract: Quantum mechanics is introduced following Plank's anzatz and wave-particle duality. Basic concept of quantum information processing is reviewed with the help of entangled states. Mathematical connection between the quantum teleportation, the most unique feature of quantum information processing, and the black hole final state is studied taking into account the non trivial spacetime geometry. This would enable us to put together the universal quantum teleportation and the black hole evaporation in the unified mathematical footing. For a renormalized post selected final state of outgoing Hawking radiation, we found that the information content, quantified by the mixedness of the state, is preserved only in the special case of final-state boundary condition in the micro-canonical form, which resembles perfect teleportation channel. It is also found that the Hawking radiation is dependent on initial condition of the black hole formation. Part of the dark matter can be explained by the primordial black hole in coherent state as an initial condition. It is also found that one of the most sacred theorems in quantum mechanics, the No-cloning theorem, can be circumvented in the presence of closed timeline curve. This effect may also shed the light on the formation of life from the matter.
