海冰对水下量子通信信道性能的影响
摘要
Objective Quantum communication uses the quantum state as an information source to achieve the effective transmission of the information of quantum state carries.It has the advantages of high security, high transmission speed, and large communication capacity and is thus a hotspot in the current communication field.However, when an equivalent optical signal is transmitted underwater, it is inevitably affected by environmental factors, resulting in the degradation of transmission performance.Sea ice is one of the important factors that affect the transmission of optical quantum signals underwater.It is composed of freshwater ice crystals, brine bubbles, and bubbles containing salt.When an optical quantum signal is transmitted underwater, the bubbles, brine bubbles, and other microbial particles in sea ice absorb and
