退相干的精度检验

A precision test of decoherence

J. R. Anglin, W. H. Zurek

摘要:

带电粒子在导电板上的运动受到对镜像电流的欧姆电阻的阻尼。粒子和平板之间的这种相互作用也必然会产生退相干,这可以通过检查经过平板的衍射粒子束产生的干涉图案来检测。由于板内的电流密度随着粒子束在其上方的高度而迅速衰减,因此退相干的强度应该在很宽的范围内可调,允许人们通过经典行为来探测量子的全部范围。

英文摘要:

The motion of a charged particle over a conducting plate is damped by Ohmic resistance to image currents. This interaction between the particle and the plate must also produce decoherence, which can be detected by examining interference patterns made by diffracted particle beams which have passed over the plate. Because the current densities within the plate decay rapidly with the height of the particle beam above it, the strength of decoherence should be adjustable across a wide range, allowing one to probe the full range of quantum through classical behaviour.
