Nearly one century after the birth of quantum mechanics, parity–time symmetry is revolutionizing and extending quantum theories to include a unique family of non-Hermitian Hamiltonians. While conceptually striking, experimental demonstration of parity–time symmetry remains unexplored in quantum electronic systems. The flexibility of photonics allows for creating and superposing non-Hermitian eigenstates with ease using optical gain and loss, which makes it an ideal platform to explore various non-Hermitian quantum symmetry paradigms for novel device functionalities. Such explorations that employ classical photonic platforms not only deepen our understanding of fundamental quantum physics but also facilitate technological breakthroughs for photonic applications. Research into non-Hermitian photonics therefore advances and benefits both fields simultaneously.

基于奇偶时间对称性的非赫米特光子学
量子力学诞生后近一个世纪,奇偶时间对称性正在革新和扩展量子理论,使其包括非赫米特哈密顿量的独特族。尽管从概念上讲引人注目,但量子电子系统中仍未探索奇偶时间对称性的实验证明。光子学的灵活性允许使用光学增益和损耗轻松创建和叠加非赫米特本征态,这使其成为探索各种非赫米特量子对称范例以实现新型器件功能的理想平台。使用经典光子平台的此类探索不仅加深了我们对基本量子物理学的理解,而且促进了光子应用的技术突破。
