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.

WebThis method requires quantification of distinguishability and photon purity parameters. The photon state purity is estimated using the calculated Joint Spectral Amplitude as shown in figure 2 , taking account of the non-ideal placement of the spectral filters, from which we estimate a single source purity of 0.97.
