我们提出了一个实验来观察单个电子的干扰，因为它是沿着两个平行的准一维通道被困在一个单一的最小的旅行周期性电场传输。该实验装置是基于声表面波的量子处理器的改进。通过在两个通道之间产生空间波函数的叠加并经由横向电场或磁场引起相对相移来实现干涉。这种干涉可以用来估计电子在这种固态器件中的退相干时间。
We propose an experiment to observe interference of a single electron as it is transported along two parallel quasi-one-dimensional channels trapped in a single minimum of a traveling periodic electric field. The experimental device is a modification of the surface-acoustic-wave-based quantum processor. Interference is achieved by creating a superposition of spatial wave functions between the two channels and inducing a relative phase shift via either a transverse electric field or a magnetic field. The interference can be used to estimate the decoherence time of an electron in this type of solid-state device.
