Popis:	Blind quantum computation (BQC) is one of the most promising alternatives to solve the shortage of quantum resources in the implementation of quantum computations. However, in most reported studies on decoy-state BQCs, the source intensities are actively modulated, which, unfortunately, results in side-channel leakage and undermines system security. In this paper, we present a passive decoy-state BQC scheme with a heralded single-photon source that circumvents this problem skillfully, improving system security. Moreover, simulation results show that our passive scheme can even outperform other active schemes in the generation efficiency of blind states when using state-of-the-art equipment.
