量子器件是利用量子效应来构筑电子器件的器件总称。因为只有纳米微小结构下才能出现显著的量子效应,所以量子电子器件属于纳器件。当常规器件的特征尺寸达到与半导体中的电子平均波长(约几纳米)相当时,由于量子隧道效应,使MOSFET作为开关的功能失效,从而使其不能再成为信息处理芯片的基本单元,而量子器件则不受此限制。当前提出的各种
Quantum devices are devices that use quantum effects to construct electronic devices. Because only under the microstructure of nano can have significant quantum effects, quantum electronic devices belong to the device. When the characteristic size of a conventional device reaches a value equivalent to the average electron wavelength in semiconductors (about a few nanometers), the MOSFET as a switch fails its function due to the quantum tunneling effect so that it can no longer become a basic unit of an information processing chip, and the quantum Devices are not subject to this limitation.
