Coherent manipulation of single electrons driven by surface acoustic waves

Abstract

In the field of quantum electron optics, where quantum optics experiments are performed using propagating electrons, quantum states of finite-size wave packets of single electrons should be manipulated. Among various types of wave packets, a single electron confined in a moving potential of a surface acoustic wave (SAW) serves as the smallest wave packet. In this article, we discuss transfer of single electrons by SAWs and control of the SAW-driven quantum transport.
