非简并光学参量放大器线宽对纠缠增强的影响
Influence of the Cavity Bandwidth of a NOPA on Entanglement Enhancement
纠缠增强 非简并光学参量放大器 线宽 entanglement enhancement non-degenerate optical parametric amplifier cavity bandwidth
摘要
非简并光学参量放大器可以有效地增强其注入纠缠态光场的纠缠度。但是由于光学参量放大器具有一定的线宽,所以不可能实现整个频率范围内的纠缠增强。为此,在本文中我们分析了光学参量放大器线宽对纠缠增强效率的影响,为今后开展宽频纠缠增强提供参考。
Abstract
It has been demonstrated that non-degenerate optical parametric amplifier (NOPA) made a remarkable enhancement of quantum entanglement. However, it is impossible to realize the entanglement enhancement in the whole frequency region due to the limitation of cavity bandwidth of a NOPA. In this paper, we investigate how the cavity bandwidth makes the influence on the entanglement enhancement, which should provide some references for the research on the broadband entanglement enhancement.
