Robust Semi-Quantum Summation over a Collective-Dephasing Noise Channel

Quantum summation is one of the various applications in secure multi-party computation. However, most existing quantum protocols assume that participants possess all devices. Considering future applications, capability must be adjusted before it can put into practical use. Although Boyer et al. proposed semi-quantum environment could used to solve this problem; another problem interference by noise. In 2022, Ye a two-party (SQS) protocol resistant collective noise, which two classical accomplish their private binary sequences with assistance semi-honest third party. They proved SQS eavesdropping attacks. This paper unveils risks information leakage al.’s protocol. If aforementioned security issues are not resolved, may able perform computations securely. Fortunately, against collective-dephasing noise study free from issue as well addition, efficiency four times higher than protocol, effectively improve utilization rate.
