We propose an experimental setup to test the effect of curved spacetime upon the extraction of entanglement from the quantum field vacuum to a pair of two-level systems. We consider two superconducting qubits coupled to a dc-SQUID array embedded into an open microwave transmission line, where an external bias can emulate a spacetime containing a traversable wormhole. We find that the amount of vacuum entanglement that can be extracted by the qubits depends on the wormhole parameters. At some distances qubits which would be in a separable state in flat spacetime would become entangled due to the analogue wormhole background.

通过模拟虫孔纠缠超导量子位

我们提出了一个实验装置，以测试弯曲时空对从量子场真空到一对两能级系统的纠缠提取的影响。我们考虑两个超导量子位，它们耦合到嵌入开放微波传输线中的dc-SQUID阵列，其中外部偏置可以模拟包含可穿越虫洞的时空。我们发现，量子位可以提取的真空缠结量取决于虫洞参数。在某些距离处，由于模拟虫洞的背景，在平坦时空中处于可分离状态的量子位会纠缠在一起。
