Pseudo-Random Unitary Operators for Quantum Information Processing

摘要: In close analogy to the fundamental role of random numbers in classical information theory, operators are a basic component quantum theory. Unfortunately, implementation unitary on processor is exponentially hard. Here we introduce method for generating pseudo-random that can reproduce those statistical properties most relevant tasks. This requires fewer resources, and hence enables practical application communication processing protocols. Using nuclear magnetic resonance processor, were able realize pseudorandom expected distribution matrix elements.
