Superposition and Entanglement: Pillars of Quantum Information   Processing
  This article discusses the important primitives of Superposition and Entanglement in Quantum Information Processing from physics point of view. System of spin-1/2 particles has been considered which presents itself as a logical and conceptual candidate to understand these concepts. The article is intended as a review of these important concepts and hopes to bring forth a conceptual framework in this regard.
