Quantum mechanics, because of its special structure, on one hand offers us possibilities for doing un-classical tasks and on the other hand imposes limitations on performing some quantum tasks. We know these limitations as no-go theorems in Quantum mechanics. Studying these no-go theorems and properties which can be used as Quantum resources, has a wide variety of applications in Quantum information and Quantum computation, also they can lead us to a deeper understanding of the Quantum mechanics theory.One of these non-classical properties is Superposition. Quantum superposition is both a source for other Quantum properties like entanglement, and a Quantum resource for Quantum tasks. But...
