“…Unlike traditional encryption techniques, physical layer security techniques [8] utilize the inherent properties of the wireless channel to provide more basic security for wireless communications. Array antenna [9] is an emerging multi-antenna physical layer security technique that utilizes the difference between the desired channel and the eavesdropping channel to achieve secure transmission of information [10,11]. Currently, there are still problems in the theoretical research and practical application of array antenna physical layer security technology that need to be urgently addressed.…”

Aiming at the problem that the traditional physical layer technology cannot realize secure transmission due to the large number of users and wide dispersion in the multicast system, a layered transmission method is proposed, and a scheme for the secure transmission of the multicast group physical layer is designed. Firstly, the hierarchical transmission system model is established. Then, the array weighted vector of each layer is optimized according to the design criterion of maximizing the artificial noise interference power. At the same time, in the case where the number of users in a single multicast group is greater than the number of transmitting antennas, a multicast grouping strategy is introduced, and the singular value decomposition and Lagrange multiplier algorithms are utilized to obtain the optimal solution. Simulation results show that the proposed method can realize the secure communication of users with different distances in the same direction and can distinguish the multicast users with the same direction angle and different distances under the premise of mutual non-interference, thus realizing the secure communication of large-scale multicast users.

“…Thus far, problems in the fields of chemistry and fluid dynamics, as well as thermodynamics and power electronics, have exploited the use of quantum algorithms. The same trend is developing in electromagnetic engineering, where quantum computing has been used to design antenna arrays [19] and metasurfaces [20]. The accurate computation of electric and magnetic eigenmodes of waveguides with arbitrary cross sections [21] is a challenging task that requires sophisticated numerical methods to improve the associated computational complexity [22].…”

Current quantum computers (QCs) belong to the noisy intermediate-scale quantum (NISQ) class, characterized by noisy qubits, limited qubit capabilities, and limited circuit depth. These limitations have led to the development of hybrid quantum-classical algorithms that split the computational cost between classical and quantum hardware. Among the hybrid algorithms, the variational quantum eigensolver (VQE) is mentioned. The VQE is a variational quantum algorithm designed to estimate the eigenvalues and eigenvectors of a system on universal-gate quantum architectures. A canonical problem in electromagnetics is the computation of eigenmodes within waveguides. Following the finite difference method, the wave equation can be recast as an eigenvalue problem. This work exploits the quantum superposition and entanglement in quantum computing to solve the square waveguide mode problem. This algorithm is expected to demonstrate exponentially efficiency over classical computational techniques as the qubit count increases. The simulations were performed on IBM's three-qubit quantum simulator, Qasm IBM Simulator. A shot-based simulation was performed considering computationally based measurements of the quantum hardware. The results of the probabilistic readout, reported in terms of 2-D eigenmode field distributions, are close to ideal values with a few number of qubits, confirming the possibility to exploit the quantum advantage to formulate innovative eigensolvers.
