Research Abstract

Quantum functional networks are constructed by using entanglement or differently-defined nonclassical correlation between subsystems of a quantum multipartite system. In this research, we performed basic mathematical researches on the correlation and discussed its relation with a realistic transmission channel. We also introduced measures to understand the amount of involved nonclassical correlation in order for economizing quantum resources.
