Quantum Search Algorithm for Binary Constant Weight Codes
Kein Yukiyoshi, Naoki Ishikawa
A binary constant weight code is a type of error-correcting code with a wide range of applications. The problem of finding a binary constant weight code has long been studied as a…
Qubit Reduction and Quantum Speedup for Wireless Channel Assignment Problem
Yuki Sano, Masaya Norimoto, Naoki Ishikawa
In this paper, we propose a novel method of formulating an NP-hard wireless channel assignment problem as a higher-order unconstrained binary optimization (HUBO), where the Grover…
Quantum Algorithm for Higher-Order Unconstrained Binary Optimization and MIMO Maximum Likelihood Detection
Masaya Norimoto, Ryuhei Mori, Naoki Ishikawa
In this paper, we propose a quantum algorithm that supports a real-valued higher-order unconstrained binary optimization (HUBO) problem. This algorithm is based on the Grover adapt…
Noncoherent Massive MIMO with Embedded One-Way Function Physical Layer Security
Yuma Katsuki, Giuseppe Thadeu Freitas de Abreu, Koji Ishibashi +1
We propose a novel physical layer security scheme that exploits an optimization method as a one-way function. The proposed scheme builds on nonsquare differential multiple-input mu…
