# Transporting and manipulating single electrons in surface-acoustic-wave minima

## TL;DR

This paper reviews how surface acoustic waves can trap and move single electrons in quantum dots, enabling applications like current standards, single-photon emission, and electron transfer, while exploring non-adiabatic effects.

## Contribution

It provides a comprehensive overview of using SAWs for single-electron manipulation and discusses recent advances and potential applications.

## Key findings

- SAWs can create moving quantum dots trapping single electrons
- SAW-based systems can serve as current standards and single-photon sources
- Transfer of electrons between quantum dots using SAWs is feasible

## Abstract

A surface acoustic wave (SAW) can produce a moving potential wave that can trap and drag electrons along with it. We review work on using a SAW to create moving quantum dots containing single electrons, with the aims of developing a current standard, emitting single photons, transferring single electrons between static quantum dots, and investigating non-adiabatic effects.
