Engineered Dissipation for Quantum Information Science

Patrick M. Harrington, Erich Mueller, Kater Murch

AI总结:

本综述阐述了量子器件中受控耗散的作用,介绍了耗散工程在量子测量、态制备等方面的应用,及其对实现实用化量子信息处理的意义。

摘要:

量子信息处理依赖于在大量不受控的环境自由度存在的情况下对非经典态的精确控制,这需要精心调控相关自由度与该环境的相互作用方式。这类相互作用通常被视为有害的,因为它们会耗散能量并使量子态退相干。尽管如此,在受控条件下,耗散是操控量子信息的重要工具:耗散工程可实现量子测量、量子态制备和量子态稳定。量子器件技术的进步以特征相干时间的提升和量子控制的可扩展架构为标志,与此同时,这类连接量子与经典自由度的耗散工程工具也得到了发展。本综述将耗散作为量子器件测量与控制的一个基本方面进行阐述,并重点介绍了耗散工程在量子纠错和量子模拟中的作用,这些作用可推动实现实用规模的量子信息处理。

英文摘要:

Quantum information processing relies on precise control of non-classical states in the presence of many uncontrolled environmental degrees of freedom -- requiring careful orchestration of how the relevant degrees of freedom interact with that environment. These interactions are often viewed as detrimental, as they dissipate energy and decohere quantum states. Nonetheless, when controlled, dissipation is an essential tool for manipulating quantum information: Dissipation engineering enables quantum measurement, quantum state preparation, and quantum state stabilization. The progress of quantum device technology, marked by improvements of characteristic coherence times and extensible architectures for quantum control, has coincided with the development of such dissipation engineering tools which interface quantum and classical degrees of freedom. This Review presents dissipation as a fundamental aspect of the measurement and control of quantum devices and highlights the role of dissipation engineering for quantum error correction and quantum simulation that enables quantum information processing on a practical scale.
