Coherent manipulation of single electrons driven by surface acoustic waves

Abstract

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