Abstract

Quantum non-Gaussian states of photons and phonons are conclusive and direct witnesses of higher-than-quadratic nonlinearities in optical and mechanical processes. Moreover, they are proven resources for quantum sensing, communication and error correction with diverse continuous-variable systems. This review introduces theoretical analyses of nonclassical and quantum non-Gaussian states of photons and phonons. It recapitulates approaches used to derive operational criteria for photons tolerant to optical losses, their application in experiments and their nowadays extension to quantum non-Gaussian photon coincidences. It extends to a recent comparison of quantum non-Gaussianity, including robustness to thermal noise, and sensing capability for high-quality phononic Fock states of single trapped cooled ions. The review can stimulate further development in the criteria of quantum non-Gaussian states and experimental effort to prepare and detect such useful features, navigating the community to advanced quantum physics and technology.

光和原子的量子非高斯性
光子和声子的量子非高斯态是光学和机械过程中高二次非线性的决定性和直接见证。此外,它们是各种连续变量系统的量子传感,通信和纠错的成熟资源。本文介绍了光子和声子的非经典态和量子非高斯态的理论分析。它概述了用于导出光损失耐受光子的操作准则的方法,它们在实验中的应用以及它们现在在量子非高斯光子巧合中的扩展。它扩展到最近的量子非高斯性的比较,包括对热噪声的鲁棒性,以及对单个捕获的冷却离子的高质量声子Fock态的传感能力。这篇综述可以刺激量子非高斯态标准的进一步发展,以及准备和检测这些有用特征的实验努力,引导社区走向先进的量子物理和技术。
