Photonic Chips for Universal Quantum Computing: Retrospective and Prospective
An arXiv review article surveys progress in integrated photonic quantum chips as a route to fault-tolerant photonic quantum computing. It argues that integrated photonics offer compact footprints, greater programmability, and better stability than bulk-optics setups, which are needed for large-scale computation.

Within two years, integrated photonic chips could become the default testbed for validating photonic fault-tolerance protocols, displacing bulk-optics demonstrations.
The abstract's emphasis on compactness, programmability, and stability directly addresses the reproducibility and alignment problems that make bulk-optics experiments hard to scale. Existing programmable integrated photonic processors already allow reconfigurable interferometers, and if this review consolidates design trade-offs for fault tolerance, more groups may adopt chips as a common platform for benchmarking fusion-based or cluster-state schemes.
