光纤通信波段强度差压缩态光场的实验制备
Generation of Intensity Difference Squeezed State of Light at Optical Fiber Communication Wavelength
摘要
强度差压缩态光场是指两束光场的强度差起伏低于对应量子噪声极限的非经典光场, 由于其两束子模具有较强的强度关联而被用于量子成像、量子随机数产生技术中, 此外, 又由于其光场强度远高于压缩态光场、纠缠态光场等非经典光场而被广泛用于量子高灵敏测量中。本文利用运转于阈值以上的非简并光学参量振荡器制备了13 μm强度差压缩态光场, 它作为一种双色关联光场可以为制备多色纠缠态光场以及开展量子计算奠定基础。
Abstract
Because of the two sub-modes possessing strong quantum correlation, intensity difference squeezed state of light is utilized in quantum imaging and quantum random number generation technique. Moreover, it is widely used in quantum high sensitivity measurement due to its higher intensity than that of other nonclassical optical states like squeezing and entanglement. In this paper, an intensity difference squeezed state of light at wavelength of 13 μm has been generated by a non-degenerate optical parametric oscillator. As a kind of two-color correlated optical state, it can be applied in generation of multi-color entanglement and pave the way to quantum computation.
