我们报告测量的电磁场的正交在两个频率f1=7 GHz和f1=7.5 GHz的隧道结放置在非常低的温度和激发频率f1+f2的辐射发射的相关性。我们证明了双模压缩的存在和Bell不等式的破坏，从而证明了在隧道结辐射的量子散粒噪声中纠缠的存在。
We report measurements of the correlations between electromagnetic field quadratures at two frequencies f1=7 GHz and f1=7.5 GHz of the radiation emitted by a tunnel junction placed at very low temperature and excited at frequency f1+f2. We demonstrate the existence of two-mode squeezing and violation of a Bell-like inequality, thereby proving the existence of entanglement in the quantum shot noise radiated by the tunnel junction.
