我们通过实验证明了在局部滤波操作下两种形式的双量子位混合态的最优纠缠蒸馏。是物理。科学通报，2016,(1)(01)(01)[j]。原则上，我们的设置可以很容易地应用于从任意两个量子位部分混合状态中提取纠缠。我们还测试了从混合状态的第一种形式蒸馏状态的clauser - horn - shinmony - holt不等式的违反，以显示其“隐藏的非局域性”。
We experimentally demonstrate optimal entanglement distillation from two forms of two-qubit mixed states under local filtering operations according to the constructive method introduced by [F. Verstraete, Phys. Rev. A 64, 010101(R) (2001)10.1103/PhysRevA.64.010101]. In principle, our setup can be easily applied to distilling entanglement from arbitrary two-qubit partially mixed states. We also test the violation of the Clauser-Horne-Shinmony-Holt inequality for the distilled state from the first form of mixed state to show its "hidden nonlocality."
