Multiphoton quantum walks have the potential to demonstrate an undisputed quantum advantage through the boson-sampling algorithm.
“Further attention has been devoted to the computational complexity of multiphoton quantum walks, which has the potential to demonstrate an undisputed quantum advantage through the boson-sampling algorithm (13–19).”
From Two-photon quantum walk in a multimode fiber (2016) · cites this paper as [19]
The Introduction describes boson sampling through multiphoton interference and says a larger experiment could provide strong evidence for quantum computational supremacy. It does not establish that the advantage would be undisputed: the hardness argument depends on computational assumptions, and the Discussion allows that more efficient classical algorithms may be possible. The cited paper does not explicitly call the process a multiphoton quantum walk. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
