论文摘要
这篇综述涵盖了最新的理论和实验努力,以将光的连续变量量子技术扩展到“高斯”量子状态(例如相干和挤压状态)之外,将其应用于具有负功能的“非高斯”状态的域。从通过参数下转换产生的单个和两模式真空状态相关的基本高斯非古老,并应用一组标准工具,例如线性干涉仪,相干状态注入以及有条件的同源性和光子数量测量值,可以实现多种光学状态和相关量化的量子,并可以在基本上进行多种多样的处理。我们对这些方法进行了系统的综述,关注其实施的基本和实际方面,以及对此结果的全面概述。
This review covers recent theoretical and experimental efforts to extend the application of the continuous-variable quantum technology of light beyond "Gaussian" quantum states, such as coherent and squeezed states, into the domain of "non-Gaussian" states with negative Wigner functions. Starting with basic Gaussian nonclassicality associated with single- and two-mode vacuum states produced by means of parametric down-conversion and applying a set of standard tools, such as linear interferometry, coherent state injection, and conditional homodyne and photon number measurements, one can implement a large variety of optical states and processes that are relevant in fundamental quantum physics as well as quantum optical information processing. We present a systematic review of these methods, paying attention to both fundamental and practical aspects of their implementation, as well as a comprehensive overview of the results achieved therewith.
