单粒子非经典性检验的改进实现
Improved implementation of nonclassicality test for a single particle
摘要：
最近提出了一个单一量子比特的非经典性测试[R。Alicki和N. Van Ryn，J. Phys. A：Math. Theor. 41，062001（2008）]。我们提出了一个优化的实验实现这个测试导致46个标准差违反经典。通过从红外到可见光的移动，我们可以利用更高的效率和更低的噪声光子探测器，实现了比我们以前的结果提高5倍。
英文摘要：
Recently a test of nonclassicality for a single qubit was proposed [R. Alicki and N. Van Ryn, J. Phys. A: Math. Theor. 41, 062001 (2008)]. We present an optimized experimental realization of this test leading to a 46 standard deviation violation of classicality. This factor of 5 improvement over our previous result was achieved by moving from the infrared to the visible where we can take advantage of higher efficiency and lower noise photon detectors.
