No photonic machine offering programmability over all its quantum gates has demonstrated quantum computational advantage: previous machines^1,2 were largely restricted to static gate sequences. Earlier photonic demonstrations were also vulnerable to spoofing³, in which classical heuristics produce samples, without direct simulation, lying closer to the ideal distribution than do samples from the quantum hardware. Here we report quantum computational advantage using Borealis, a photonic processor offering dynamic programmability on all gates implemented. We carry out Gaussian boson sampling⁴ (GBS) on 216 sNature75-81https://www.ebi.ac.uk/biostudies/studies/S-EPMC9159949biostudies-literatureQuantum computational advantage with a programmable photonic processor.PMC9159949Bulmer JFFGerrits TAskarani MFMenotti MVernon ZLaudenbach FMiatto FMNam SWLavoie JMadsen LSNeuhaus LVincent TCollins MJLita AEQuesada NDhand IHelt LGVaidya VDRortais FfalseQuantum computational advantage with a programmable photonic processor.A quantum computer attains computational advantage when outperforming the best classical computers running the best-known algorithms on well-defined tasks.
