Contributed to the Jiuzhang photonic sampling experiments and their programmable successor, advancing the experimental study of quantum computational advantage with large optical systems.
arXiv / SciencearXiv / Physical Review LettersUniversity of Science and Technology of ChinaLu adds a distinct experimental perspective to the directory: photonic sampling as a test of quantum computational advantage. He is a co-author of the 2020 Jiuzhang result and the 2021 phase-programmable follow-up, which brought together squeezed-light sources, interferometers and photon detection. His contribution is represented through those original papers and his verified USTC identification. The profile keeps the claim bounded: these experiments address specialized sampling problems, and their published comparisons depend on the classical algorithms and assumptions used at the time.

Work, in context- 2020
Jiuzhang photonic sampling
Lu co-authored the experiment “Quantum computational advantage using photons,” published in Science. The team used squeezed-light inputs, a 100-mode interferometer and photon detection to perform Gaussian boson sampling, observing up to 76 output photon clicks. The paper evaluates samples against several alternative hypotheses.

Programmable Gaussian boson sampling
Lu co-authored the Jiuzhang 2.0 work using stimulated squeezed light. The experiment reported up to 113 detection events in a 144-mode photonic circuit and allowed input phases to be tuned. The paper also introduced a validation method using smaller, computationally tractable subsystems.

Keep in perspective
Gaussian boson sampling is a specialized task, not general-purpose quantum computing. Published advantage estimates depend on classical baselines and do not establish a permanent speed record. Results are team achievements.
