论文摘要
我们提出了一个实验设置，以测试弯曲时空对从量子场真空到一对人造原子的纠缠提取的作用。特别是，我们考虑了两个超导量子位，该量子位耦合到嵌入开放的微波传输线中的DC板阵列，其中合适的外部偏见能够模拟一个时空，其中包含可遍布的蠕虫孔。我们发现，超导柜可以提取的真空纠缠量取决于虫洞的参数。由于存在有效的虫洞背景，因此在某些距离处将在平坦的时空中保持纠缠。
We propose an experimental setup to test the role of curved spacetime on entanglement extraction from the vacuum of a quantum field to a pair of artificial atoms. In particular, we consider two superconducting qubits coupled to a dc-SQUID array embedded into an open microwave transmission line, where a suitable external bias is able to mimic a spacetime containing a traversable wormhole. We find that the amount of vacuum entanglement that can be extracted by the superconducting qubits depends on the parameters of the wormhole. At some distances qubits that would remain separable in flat spacetime become entangled due to the presence of the effective wormhole background.
