Three-User Classical-Quantum Interference Channels with secrecy constraints: a Mixed Strong-Very Strong Interference

In recent years, many studies have focused on the K-user interference channels and multiple access channels. In this paper, based on quantum information theory, we want to derive an achievable secrecy rate region for three-user classical-quantum interference wiretap channel with a mixed strong-very strong interference. We consider an assumption: Each receiver gets a strong and a very strong interference signal. We first divide the main channel into three separate classical-quantum multiple access wiretap channels and derive an achievable secrecy rate region for each of them. Then, an achievable secrecy rate region is calculated for three-user classical-quantum interference wiretap channel with mixed strong-very strong interference
