Regina Kruse, Craig S. Hamilton, Linda Sansoni, Sonja Barkhofen, Christine Silberhorn, Igor Jex

摘要:

自从玻色子采样的发展以来,人们一直在寻求构建更有效和实验可行的协议来测试从光子态采样的计算复杂性。在本文中,我们解释和推广的结果[物理。119,170501(2017)]。我们推导出一个表达式,该表达式将从高斯态测量特定光子输出模式的概率与\textit{hafnian}矩阵函数联系起来,并使用它来设计高斯玻色子采样协议。然后,我们讨论了该协议相对于其他光子协议的优点和高斯玻色子采样的实验要求。最后,我们将其与以前最一般的协议,散点玻色子采样[物理学评论快报。113,100502(2014)]

英文摘要:

Since the development of Boson sampling, there has been a quest to construct more efficient and experimentally feasible protocols to test the computational complexity of sampling from photonic states. In this paper we interpret and extend the results presented in [Phys. Rev. Lett. 119, 170501 (2017)]. We derive an expression that relates the probability to measure a specific photon output pattern from a Gaussian state to the \textit{hafnian} matrix function and us it to design a Gaussian Boson sampling protocol. Then, we discuss the advantages that this protocol has relative to other photonic protocols and the experimental requirements for Gaussian Boson Sampling. Finally, we relate it to the previously most general protocol, Scattershot Boson Sampling [Phys. Rev. Lett. 113, 100502 (2014)]
