量子测量中的全局信息平衡

Global information balance in quantum measurements

Francesco Buscemi, Masahito Hayashi, Michal Horodecki

摘要:

我们对量子测量过程进行了信息论分析,得到了量子测量中的全局信息平衡,其形式为量子互熵的闭链方程。我们的平衡提供了一个紧密的和一般的熵信息干扰权衡,并解释其背后的物理机制。最后,单结果的情况下,即测量后选择的情况下,进行了简要讨论。

英文摘要:

We perform an information-theoretical analysis of quantum measurement processes and obtain the global information balance in quantum measurements, in the form of a closed chain equation for quantum mutual entropies. Our balance provides a tight and general entropic information-disturbance trade-off, and explains the physical mechanism underlying it. Finally, the single-outcome case, that is, the case of measurements with post-selection, is briefly discussed.
