论文摘要
在微观量子系统中，一个人无法同时测量粒子和波性能。但是，对于宏观量子系统而言，这可能并非如此。作为演示，我们建议测量超导体中两个缝隙的局部宏观电流。根据基于宏观伪波函数的线性化金兹堡 - 兰道方程的理论，在Bohmian的量子力学解释中，测得的电流的流线应与粒子轨迹相同。通过明确的计算，我们发现流线应显示出特征性的摇摆，这是量子干扰的结果。
In a microscopic quantum system one cannot perform a simultaneous measurement of particle and wave properties. This, however, may not be true for macroscopic quantum systems. As a demonstration, we propose to measure the local macroscopic current passed through two slits in a superconductor. According to the theory based on the linearized Ginzburg-Landau equation for the macroscopic pseudo wave function, the streamlines of the measured current should have the same form as particle trajectories in the Bohmian interpretation of quantum mechanics. By an explicit computation we find that the streamlines should show a characteristic wiggling, which is a consequence of quantum interference.
