摘要
在这项工作中,我们将考虑星形网络场景,即中心方是可信的,而所有边缘方(数量为 n)都是不可信的。网络转向是通过 n 个局部隐藏状态模型定义的,该模型可被视为一种特殊的 n 个局部隐藏变量模型。我们将构建两种不同的充分条件,即非线性转向不等式和线性转向不等式,来验证星型网络中的量子转向。在线性转向不等式的基础上,将讨论如何用固定测量检测网络转向。
In this work, we will consider the star network scenario where the central party is trusted while all the edge parties (with a number of n) are untrusted. Network steering is defined with an n local hidden state model which can be viewed as a special kind of n local hidden variable model. Two different types of sufficient criteria, nonlinear steering inequality and linear steering inequality will be constructed to verify the quantum steering in a star network. Based on the linear steering inequality, how to detect the network steering with a fixed measurement will be discussed.
期刊介绍:
General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology.
Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate).
EPL also publishes Comments on Letters previously published in the Journal.
