Abstract

In waveguide quantum electrodynamics (QED) systems, atomic radiation emission is shaped by photonic environment and collective atom interactions, offering promising applications in quantum technologies. In particular, atom-photon bound states, inhibiting a complete spontaneous decay of the atom, can be realized through waveguide dispersion engineering or by utilizing giant atoms. While steady-state bound states are well understood, transient or virtual bound states remain less explored. Here, we investigate transient atom-photon bound states, arising from initial atom-photon entanglement, and propose methods to slow down spontaneous atomic decay.

虚原子-光子束缚态与自发发射控制。

在波导量子电动力学（QED）系统中，原子辐射发射是由光子环境和集体原子相互作用形成的，在量子技术中有很好的应用前景。特别是原子-光子束缚态，抑制原子的完全自发衰变，可以通过波导色散工程或利用巨原子来实现。虽然稳态束缚态被很好地理解，但暂态或虚束缚态仍然很少被探索。在这里，我们研究了由初始原子光子纠缠产生的瞬态原子光子束缚态，并提出了减缓自发原子衰变的方法。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
