Efficient Quantum Algorithm for Phase Optimization of 1-Bit RIS-Assisted MIMO Communication System
Soumyadip Paul, Neel Kanth Kundu
We propose a Quantum Approximate Optimization Algorithm with a deterministic linear ramp schedule (QAOA-LR) for phase optimization of a 1-bit RIS-assisted MIMO communication system. Each RIS element is restricted to a binary phase shift of 0 or π, turning the passive beamforming…
