Webpartial photon distinguishability in GBS, except for a re-cent paper38 claiming to extend their results for partial distinguishability in AABS to that in GBS. The results of Ref.38 are somewhat unsatisfactory in the sense that their results for GBS must be applied in a context simi-lar to AABS.

Optimal photonic indistinguishability tests in multimode networks

WebUnlike universal quantum computation, boson sampling merely requires indistinguishable photons, linear state evolution, and detectors. We benchmarked our QBSM with three and four photons and analyzed sources of sampling inaccuracy. Scaling up to larger devices could offer the first definitive quantum-enhanced computation. WebNov 26, 2024 · Recently classical simulations have been expanded to consider practical issues such as photon distinguishability, based on a rich collection of theoretical work in this area [ 16 – 28 ]. Renema et al [ 29] demonstrated that boson sampling with partially-distinguishable photons can be simulated in time which grows polynomially with n. p-touch pt-2430pc download
