The Role of Unitary and AntiUnitary Operators for NoGo Theorems in Quantum Computing
G. Conte · International Journal of Computer Applications · 2015
No-go theorems for quantum computing give a mathematical proof that quantum dynamic should be linear as well unitary.In this paper we analyze in a detailed way the role of linearity and unitarity for no-cloning theorem; also we introduce a nogo theorem for the square root of Not gate √Not which can never would work in the complete complex Hilbert space.
