摘要:

随着时代的进步发展, 量子科学技术在国家安全, 社会经济高质量发展中的重要性逐渐显露. 如何操控量子态来储存、传递和处理信息一直是量子计算、量子通讯等量子信息科学研究中的关键性问题. 有别于传统认知, 量子系统允许某些在经典世界中不存在的控制方式, 反事实量子调控便是其一. 作为一种非局域的量子调控方式, 在反事实量子调控的过程中, 没有任何实际物质粒子、能量在调控方和被调控方之间输运交换. 通过对反事实量子调控的研究, 人们不仅深入理解了非局域量子现象, 也发现了其在样本无伤成像和隐身探测技术等应用上的重大潜在价值. 本工作介绍了反事实量子调控的基本概念, 回顾了相应的理论证明, 也对相关的实验验证、非局域性研究以及应用性探索做了阐述.

Abstract:

With the progress and development of society, the importance of quantum technology in national security and the high-quality development of social economy has gradually emerged. In research on quantum information, such as quantum computing and quantum communication, manipulating quantum states to store, transmit, and process information has always been a critical problem. Contrary to conventional knowledge, quantum systems enable unique control that does not exist in the classical world, one of which is counterfactual quantum control. As a nonlocal quantum control method, there is no exchange of any physical particles and energy between the controller and the controlled target during the control process. By investigating counterfactual quantum control, we not only clarified non-local quantum phenomena but also discovered vital potential applications, such as noninvasive imaging and stealth detection technology. In this paper, we introduce the concepts of counterfactual quantum control and the corresponding theory. In addition, we present a review of related experimental verifications and research on non locality and its applications.

Key words: counterfactual quantum control, non locality, quantum interference, interaction-free measurement, quantum Zeno effect
