摘要

Abstract Multiparty quantum communication attracts continuous attention due to the better adaptability for the future quantum internet than point‐to‐point communication. Unfortunately, the imperfections of practical devices are exploited to take side‐channel attacks which threatens the security of practical multiparty quantum communication. We propose a three‐party detector‐device‐independent quantum secret sharing (DDI‐QSS) protocol based on hyper‐encoding and single‐photon Bell‐state measurement. It works in a deterministic way. The hyper‐encoding circuit and single‐photon Bell‐state measurement device can be built with only linear optical elements, which makes the protocol more practical. Different from the measurement‐device‐independent setting, the DDI‐QSS protocol does not require the multi‐photon interference of photons from independent sources. We prove that it is secure against general entanglement‐measure attacks launched by a dishonest participant.
