四波混频放大器中的强低频量子关联

Strong low-frequency quantum correlations from a four-wave mixing amplifier

C. F. McCormick, A. M. Marino, V. Boyer, P. D. Lett

摘要:

我们表明,一个简单的计划的基础上的非简并四波混频在热原子蒸气表现得像一个近乎完美的相位不敏感的光放大器,它可以产生明亮的孪生光束与测量的量子噪声减少强度差超过8 dB,接近最好的光学参量放大器和振荡器。腔的不存在使得系统不受外部扰动的影响,并且在很大的频率范围内观察到强的量子噪声降低。

英文摘要:

We show that a simple scheme based on nondegenerate four-wave mixing in a hot atomic vapor behaves like a near-perfect phase-insensitive optical amplifier, which can generate bright twin beams with a measured quantum noise reduction in the intensity difference of more than 8 dB, close to the best optical parametric amplifiers and oscillators. The absence of a cavity makes the system immune to external perturbations, and the strong quantum noise reduction is observed over a large frequency range.
