论文摘要
电子双裂衍射中的干扰模式是量子力学的标志。随机电动力学(SED)的一个长期存在的问题是它是否能够再现这种效应,因为干扰是量子相干性的表现。在这项研究中,我们使用激发谐波振荡器直接测试SED中的量子特征。我们使用两种反向传播的二分激光脉冲来将地面谐波振荡器促进挤压的schrödinger猫状态。在两个良好分离的波袋重组后,在量子概率分布中出现了干扰模式,但在SED概率分布中不存在。因此,我们给出了一个反例,拒绝SED作为量子力学的有效替代方案。
The interference pattern in electron double-slit diffraction is a hallmark of quantum mechanics. A long standing question for stochastic electrodynamics (SED) is whether or not it is capable of reproducing such effects, as interference is a manifestation of quantum coherence. In this study, we use excited harmonic oscillators to directly test this quantum feature in SED. We use two counter-propagating dichromatic laser pulses to promote a ground-state harmonic oscillator to a squeezed Schrödinger cat state. Upon recombination of the two well-separated wavepackets, an interference pattern emerges in the quantum probability distribution but is absent in the SED probability distribution. We thus give a counterexample that rejects SED as a valid alternative to quantum mechanics.
