AI 中文摘要
集成光子量子芯片已成为实现容错光子量子计算机的极具前景的平台。与体光学系统相比，集成光子学具备紧凑的器件 footprint（ footprint 指器件占地面积）、更强的可编程性以及出色的稳定性，这些特性对执行大规模、计算密集型量子任务至关重要。在本综述中，我们全面概述了离散变量和连续变量通用光子量子计算的最新进展，调研了容错架构和最先进集成平台的进展，并强调了将光子系统扩展至完全容错状态必须解决的关键挑战。最后，我们概述了未来的机遇和研究方向，旨在弥合当前原理验证演示与完全可扩展量子微处理器之间的差距。
英文摘要
Integrated photonic quantum chips have emerged as a promising platform for realizing fault-tolerant photonic quantum computers. Compared with bulk-optics systems, integrated photonics offer compact device footprints, enhanced programmability, and exceptional stability, attributes that are essential for executing large-scale and computationally demanding quantum tasks. In this review, we provide a comprehensive overview of recent advances in both discrete-variable and continuous-variable universal photonic quantum computation. We survey progress in fault-tolerant architectures and state-of-the-art integrated platforms and highlight the key challenges that must be addressed to scale photonic systems toward full fault tolerance. Finally, we outline future opportunities and research directions aimed at bridging the gap between current proof-of-principle demonstrations and fully scalable quantum microprocessors.
