论文摘要
我们提出了一种新型的半分析方法,用于构建最佳的线性光学电路,用于预示3 photon GHz和2光钟状态的生产。我们对所得的光学方案提供了详细的描述和分析,该方案分别为双跑车编码的3-GHZ和贝尔状态生成提供了1/54和2/27的成功概率。我们的结果提高了3-GHz状态成功概率的已知建设性界限,对于弹道量子计算模型特别重要,这些状态为此提供了必不可少的资源。
We present a novel semi-analytical methodology to construct optimal linear optical circuits for heralded production of 3-photon GHZ and 2-photon Bell states. We provide a detailed description and analysis of the resulting optical schemes, which deliver success probabilities of 1/54 and 2/27 for dual-rail encoded 3-GHZ and Bell states generation, respectively. Our results improve the known constructive bounds on the success probabilities for 3-GHZ states and are of particular importance for a ballistic quantum computing model, for which these states provide an essential resource.
