Local Quantum Joint Entropy and Quantum Coherence Information Based on Local Quantum Bernoulli Noise
摘要
Local quantum Bernoulli noises (LQBNs) is a family of local annihilation operators and local creation operators acting on Bernoulli functions. In this paper, based on LQBNs, we define the local quantum joint entropy and local quantum coherence information. And we find local quantum entropy has a surprising property, which is not satisfies the additivity for tensor product state. Furthermore, we give some properties of local quantum coherent information based on LQBNs.
