WebThis result has triggered several multi-boson interference experiments [6–11] as well as studies of its characterization [20–24]. In its current formulation, the boson sampling problem relies only on sampling over all pos-sible subsets of detected output ports regardless of the time and the polarization associated with each detection. WebDec 19, 2024 · We propose a test of the correct functioning of a boson sampler with single-photon inputs that is based on how photons distribute among partitions of the output modes. Our method is versatile and encompasses previous validation tests based on bunching phenomena, marginal distributions, and even some suppression laws.
The output of a universal quantum computer running, for example, Shor's factoring algorithm, can be efficiently verified classically, as is the case for all problems in the non-deterministic polynomial-time (NP) complexity class. It is however not clear that a similar structure exists for the boson sampling scheme. Namely, as the latter is related to the problem of estimating matrix permanents (falling into #P-hard complexity class), it is not understood how to verify correct operation for larg…
