An adaptive quantum state-hopping communication strategy based on kangaroo entanglement hopping model
Min Nie, Rong-Yu Wei, Guang Yang, Mei-Ling Zhang, Ai-Jing Sun, and Chang-Xing Pei
Quantum communication in free space will be disturbed by natural environment such as fog and dust. However, to build a global quantum satellite wide area communication network, we must solve the problem of 24-h all-weather communication between satellite and earth. With the evolution of time, the degree of interference
