We derive two classes of multimode Bell inequalities under local realistic assumptions, which are violated only by the entangled states negative under partial transposition in accordance with the Peres conjecture. Remarkably, the failure of local realism can be manifested by exploiting wave and particle correlations of readily accessible continuous-variable states, with very large violation of inequalities insensitive to detector efficiency, which makes a strong case for a loophole-free test.
我们根据局域实在性假设推导出两类多模贝尔不等式，只有根据佩雷斯猜想，局域实在性假设下的部分转置的纠缠态才违反这些不等式。值得注意的是，通过利用易于获得的连续变量态的波和粒子相关性，可以明显地表现出局域实在性的失败，而且这些不等式的违反程度非常大，对探测器效率不敏感，这为无漏洞测试提供了强有力的证据。
