Multi-party quantum private size comparison protocol with d-dimensional Bell states

Frontiers in Physics, 2022
A feasible multi-party quantum private comparison (MQPC) protocol based on d-dimensional Bell states was proposed. In the protocol, all participants can independently encrypt their privacies and send them to a semi-honest quantum third party (TP) through
