基于检错量子态转移的容错线性光学量子计算

Fault-tolerant linear optics quantum computation by error-detecting quantum state transfer

Jaeyoon Cho

摘要:

提出了一种基于检错码的容错量子计算的线性光学实现方案。每个计算步骤都是通过将量子信息转移到嵌入错误检测能力的辅助系统中来调解的。假设光子同时受到光子损耗和退偏振的影响,得到了可扩展量子计算中光子强度的阈值区域,以及所消耗的物理资源量。与目前已知的结果相比,本方案减少了资源需求,同时产生一个可比的阈值区域。

英文摘要:

A scheme for linear optical implementation of fault-tolerant quantum computation is proposed, which is based on an error-detecting code. Each computational step is mediated by transfer of quantum information into an ancilla system embedding error-detection capability. Photons are assumed to be subjected to both photon loss and depolarization, and the threshold region of their strengths for scalable quantum computation is obtained, together with the amount of physical resources consumed. Compared to currently known results, the present scheme reduces the resource requirement, while yielding a comparable threshold region.
