论文摘要
光子和声子的量子非高斯状态是光学和机械过程中高于季度非线性的最终见证人。此外,它们是通过不同的连续变量系统进行量子感测,沟通和错误纠正的证明资源。这篇综述介绍了对光子和声子的非经典和量子非高斯状态的理论分析。它概括了用于得出耐光子损失的光子的操作标准的方法,它们在实验中的应用以及如今扩展到量子非高斯光子复合。它扩展到了量子非高斯性的最新比较,包括与热噪声的鲁棒性以及对单个捕获冷却离子的高质量音调态态的感应能力。该综述可以刺激量子非高斯州标准的进一步发展,并为准备和检测有用的特征而进行实验努力,从而使社区导航到先进的量子物理和技术。
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.
