提出了一种与设备无关的方法来证明所有纠缠态的纠缠。这是通过将状态置于量子网络中并基于状态的纠缠证据构建相关不等式来实现的。我们的方法是独立于设备的，在这个意义上，纠缠可以证明从观察到的统计数据，在最小的假设下的基础物理。从概念上讲，我们的研究结果借用了自测试领域的想法，将最近引入的测量设备无关的纠缠证人带入完全设备无关的制度。
We present a method to certify the entanglement of all entangled quantum states in a device-independent way. This is achieved by placing the state in a quantum network and constructing a correlation inequality based on an entanglement witness for the state. Our method is device independent, in the sense that entanglement can be certified from the observed statistics alone, under minimal assumptions on the underlying physics. Conceptually, our results borrow ideas from the field of self-testing to bring the recently introduced measurement-device-independent entanglement witnesses into the fully device-independent regime.
