Roadmap on nonlinear optics–focus on Chinese research
JPhys Photonics, 2023 In nonlinear optical systems, the optical superposition principle breaks down. The system’s response (including electric polarization, current density, etc) is not proportional to the stimulus it receives. Over the past half century, nonlinear optics has

Loss-tolerant operations in parity-code linear optics quantum computing [PDF]
, 2007 A heavy focus for optical quantum computing is the introduction of error-correction, and the minimisation of resource requirements. We detail a complete encoding and manipulation scheme designed for linear optics quantum computing, incorporating scalable
