Fock空间视角下的最优预报方案

Fock Space Perspective on Optimal Heralding Schemes

F. V. Gubarev

摘要:

本文研究了线性光学量子计算中最优预言方案的设计。由于[Phys. Rev. A100,022301; arXiv:1901.06178]的线性光学可行性标准,该问题允许在相关Fock空间中制定单位保真度。提出了相应的解决方法。作为应用,我们考察了几种已知的Bell态产生方案的最优性.结果表明,在六个模式和两个辅助光子的情况下,成功率2/27是次优的。

英文摘要:

We address the design of optimal heralding schemes in linear optical quantum computing context. The problem admits unit fidelity formulation in relevant Fock space, thanks to linear optic feasibility criteria of [Phys. Rev. A100, 022301; arXiv:1901.06178]. Corresponding solution methodology is presented. As an application we inspect optimality of a few known schemes of Bell states generation. It is shown that in case of six modes and two ancillary photons success rate 2/27 is suboptimal.
