Abstract

The ability to manipulate and observe phenomena on attosecond timescales has yielded groundbreaking insights into electron dynamics and the behaviour of matter exposed to intense light fields. The interdisciplinary field of attosecond science connects various research areas, including quantum optics, quantum chemistry and quantum information science. However, the intrinsic quantum effects in attosecond science have been largely ignored. In this Perspective, we discuss the latest theoretical and experimental advances in exploring and understanding quantum phenomena within attosecond science. We focus on distinguishing genuinely quantum observations from classical phenomena in the context of high-harmonic generation and above-threshold ionization. Additionally, we illuminate the often overlooked yet important role of entanglement in attosecond processes, elucidating its influence on experimental outcomes. Attosecond science is a versatile discipline for studying ultrafast dynamics in matter on the microscopic scale. This Perspective explores the theoretical and experimental developments in this field focusing on distinguishing genuinely quantum observations from classical phenomena.

阿秒科学中的量子现象

在阿秒时间尺度上操纵和观察现象的能力，使人们对电子动力学和暴露在强光场下的物质行为有了突破性的认识。阿秒科学这一跨学科领域连接着多个研究领域，包括量子光学、量子化学和量子信息科学。然而，阿秒科学中的内在量子效应在很大程度上被忽视了。在本《视角》中，我们将讨论在探索和理解阿秒科学中的量子现象方面取得的最新理论和实验进展。我们的重点是在高次谐波产生和阈值以上电离的背景下，将真正的量子观测与经典现象区分开来。此外，我们还阐明了纠缠在阿秒过程中经常被忽视但却非常重要的作用，阐明了它对实验结果的影响。阿秒科学是一门在微观尺度上研究物质超快动力学的多功能学科。本视角探讨了这一领域的理论和实验发展，重点是区分真正的量子观测和经典现象。
