标题： Two-mode Correlation of Microwave Quantum Noise Generated by Parametric Down-Conversion

摘要： 在本信中，我们报告了由约瑟夫森参数转换器对量子噪声的放大所产生的微波辐射两种模式之间的相关性的观察。 从泵浦角度看，这一过程可以视为参数向下转换。 通过一个显示对比度优于99%的干涉实验测得了这种相关性，每种模式的光子数超过二十五万。 耗散性测量和介观系统以及量子加密可以从中受益。 显示英文摘要

摘要： In this letter, we report the observation of the correlation between two modes of microwave radiation resulting from the amplification of quantum noise by the Josephson Parametric Converter. This process, seen from the pump, can be viewed as parametric down-conversion. The correlation is measured by an interference experiment displaying a contrast better than 99% with a number of photons per mode greater than two hundred and fifty thousand. Dispersive measurements of mesoscopic systems and quantum encryption can benefit from this development.
