Nonclassical light is light that cannot be described using classical electromagnetism; its characteristics are described by the quantized electromagnetic field and quantum mechanics. The most common described forms of nonclassical light are the following:

  • 非经典光是指不能用经典电动力学描述的光，其特性需要通过量子化的电磁场以及量子力学来进行描述。非经典光具有被称作的非经典噪声特性，这种特性可以在量子光学的基础上来进行理解。 最为常见的非经典光状态有以下几种： * 在单个正交分量上具有较小的噪声。常见的几种压缩态光在单个分量上要么具有较小的振幅噪声，要么具有较小的相位噪声，但在其他分量上噪声则较大。 * （或称光子数态）是指系统的光子数是已知的，但相位却尚不确定的状态。 (zh)

  • Nonclassical light is light that cannot be described using classical electromagnetism; its characteristics are described by the quantized electromagnetic field and quantum mechanics. The most common described forms of nonclassical light are the following: * Photon statistics of Nonclassical Light is Sub-Poissonian in the sense that the average number of photons in a photodetection of this kind of light shows a standard deviation that is less than the mean number of the photons. * Squeezed light exhibits reduced noise in one quadrature component. The most familiar kinds of squeezed light have either reduced amplitude noise or reduced phase noise, with increased noise of the other component. * Fock states (also called photon number states) have a well-defined number of photons (stored e.g. in a cavity), while the phase is totally undefined.
