摘要

In this study, we put forward a novel MQPC protocol of size relationship based on ODQWC with two semi-honest TPs, which can achieve the size relationship comparison of privacies between one user and the remaining users. This protocol only adopts two-particle product states as the initial quantum resource, only uses d-dimensional single particle measurements and does not employ quantum entanglement swapping operations.
