本文研究了涨落无质量标量场对同时密集编码协议的影响。构建了SDC协议的噪声模型，推导出控制SDC演化的主方程。讨论了真空涨落对不同锁定算子的SDC协议成功概率的影响。我们发现，联合成功概率是独立的锁定操作，但其他成功概率不是。对于量子傅里叶变换和双控制非算符，成功概率随两原子距离的增加而下降，而SWAP算符则不随距离的增加而下降。与SWAP操作符不同，Bob和Charlie的成功概率是不同的。对于不同的噪声区间值，不同的锁定算子具有不同的噪声鲁棒性。
In this paper, we investigate the simultaneous dense coding (SDC) protocol affected by fluctuating massless scalar field. The noisy model of SDC protocol is constructed and the master equation that governs the SDC evolution is deduced. The success probabilities of SDC protocol are discussed for different locking operators under the influence of vacuum fluctuations. We find that the joint success probability is independent of the locking operators, but other success probabilities are not. For quantum Fourier transform and double controlled-NOT operators, the success probabilities drop with increasing two-atom distance, but SWAP operator is not. Unlike the SWAP operator, the success probabilities of Bob and Charlie are different. For different noisy interval values, different locking operators have different robustness to noise.
