相位共轭输入连续变量克隆的实验验证

Experimental Demonstration of Continuous Variable Cloning with Phase-Conjugate Inputs

Metin Sabuncu, Ulrik L. Andersen, Gerd Leuchs

摘要:

我们报告的连续变量克隆的相位共轭相干态的Cerf和Iblisdir(物理评论Lett。87,247903(2001))。与Cerf和Iblisdir的建议相反,克隆转换仅使用线性光学组件、零差检测和前馈来完成。成功地获得了3个无性系,克隆率在89%左右。

英文摘要:

We report the experimental demonstration of continuous variable cloning of phase conjugate coherent states as proposed by Cerf and Iblisdir (Phys. Rev. Lett. 87, 247903 (2001)). In contrast to the proposal of Cerf and Iblisdir, the cloning transformation is accomplished using only linear optical components, homodyne detection and feedforward. Three clones are succesfully produced with fidelities about 89%.
