摘要:

我们首次报道了在无辅助过程中两个不相交的单光子之间的非局域纠缠。对于我们的实验,我们推导出一个简单而有效的方法来纠缠两个单光子使用后选择技术。光子被引导到干涉仪设置中,而不需要辅助光子来投射到贝尔态中。在通过输出端口后,光子在每一侧使用钟形状态分析仪进行分析。实验数据清楚地显示了这些光子之间的非局域相互作用,超过了CHSH不等式设定的极限,S值为2.54和24个标准差。

英文摘要:

We report for the first time in an ancilla-free process a non-local entanglement between two single photons which do not meet. For our experiment we derive a simple and efficient method to entangle two single photons using post-selection technology. The photons are guided into an interferometer setup without the need for ancilla photons for projection into the Bell-states. After passing the output ports, the photons are analyzed using a bell state analyzer on each side. The experimental data clearly shows a non-local interaction between these photons, surpassing the limit set by the CHSH-inequality with an S-value of 2.54 and 24 standard deviations.
