Penalty-Free Two-Step Optimization of Higher-Order Ising Problems for Two-Dimensional Line-Controlled RIS
Tasuku Okamoto, Naoki Ishikawa, Daisuke Kitayama +5
Reconfigurable intelligent surfaces (RISs) are often assumed to allow continuous phase control over all elements, leading to hardware cost that scales with the number of elements.…
Quantum-Accelerated Wireless Communications: Concepts, Connections, and Implications
Naoki Ishikawa, Giuseppe Thadeu Freitas de Abreu, Petar Popovski +1
Quantum computing is poised to redefine the algorithmic foundations of communication systems. While quantum superposition and entanglement enable quadratic or exponential speedups…
Grover Adaptive Search for Maximum Likelihood Detection of Generalized Spatial Modulation
Kein Yukiyoshi, Taku Mikuriya, Hyeon Seok Rou +2
We propose a quantum-assisted solution for the maximum likelihood detection (MLD) of generalized spatial modulation (GSM) signals. Specifically, the MLD of GSM is first formulated…
AFDM Chirp-Permutation-Index Modulation with Quantum-Accelerated Codebook Design
Hyeon Seok Rou, Kein Yukiyoshi, Taku Mikuriya +2
We describe a novel index modulation (IM) scheme exploiting a unique feature of the recently proposed affine frequency division multiplexing (AFDM) in doubly-dispersive (DD) channe…
