Abstract

The realization of reliable quantum channels, able to transfer a quantum state with high fidelity, is a fundamental step in the construction of scalable quantum devices. In this paper we describe a transmission scheme based on the genuinely quantum effect known as Bloch oscillations. The proposed protocol makes it possible to carry a quantum state over different distances with a minimal engineering of the transmission medium and can be implemented and verified on current quantum technology hardware.

摘要

实现能够以高保真度传输量子态的可靠量子信道，是构建可扩展量子设备的基本步骤。在本文中，我们描述了一种基于被称为布洛赫振荡的真正量子效应的传输方案。所提出的协议能够在对传输介质进行最小程度工程设计的情况下，在不同距离上携带量子态，并且可以在当前的量子技术硬件上实现和验证。
