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. © 2021 John Wiley & Sons Ltd.
