Secure Multiparty Quantum Summation Based on d-Level Single Particles

摘要

In this paper, we propose a multiparty quantum summation module d protocol based on d-level single particles (where d is a prime number). A semi-trusted additional party is introduced to help multiple participants achieve this summation task. Our protocol is more practical and efficient, because it uses only single particles rather than entangled states. After that, the Chinese remainder theorem is utilized to get the summation without module d. Furthermore, the security of our protocols is analyzed, it shows that our protocols could resist some well-known attacks.
