在这里，我们给出了一个关键的审查的可能性，实现量子泵的电荷。该物理学是基于量子绝热粒子输运理论，最初是由于无质量。我们提出的理论指导观察这种现象的实验条件。我们认为，潜在的非常准确的量化的电荷传输或电子电流可以实现，一旦这些条件近似满足。一个例子的实验装置概述，以证明实际的可能性。对这种量子器件的科学意义也作了一些评论。
Here we give a critical examination of the possibility of realizing a quantum pump of electric charges. The physics is based on the theory of quantum adiabatic particle transport initially due to Thouless. We present theoretical guidelines on the experimental conditions for observing this phenomenon. We argue that potentially very accurate quantization of charge transport or electron current can be achieved, once these conditions are approximately satisfied. An example of experimental setup is outlined to demonstrate the practical possibilities. Some comments are also made on the scientific significance of such a quantum device.
