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.…
Scalable and Near-Optimal Discrete Phase Shift Optimization for Reconfigurable Intelligent Surfaces with Over 20,000 Elements
Yuto Hama, Daisuke Kitayama, Kensuke Inaba +4
This paper proposes a novel optimization framework for discrete phase shifts of a reconfigurable intelligent surface (RIS) using a coherent Ising machine (CIM). Unlike conventional…
Ultra-high-rate detection of entangled photon pairs
Toshimori Honjo, Shigeyuki Miyajima, Shigehito Miki +5
The high-rate detection of entangled photons is essential for advancing photonic quantum information processing. Although several experimental demonstrations have been reported, th…
Model-based framework for automated quantification of error sources in quantum state tomography
Junpei Oba, Hsin-Pin Lo, Yasuhiro Yamada +6
High-quality quantum state generation is essential for advanced quantum information processing, including quantum communication, quantum sensing, and quantum computing. In practice…
10-GHz-clock time-multiplexed non-degenerate optical parametric oscillator network with a variable planar lightwave circuit interferometer
Yuya Yonezu, Kensuke Inaba, Yasuhiro Yamada +4
A coherent XY machine (CXYM) is a physical spin simulator that can simulate the XY model by mapping XY spins onto the continuous phases of non-degenerate optical parametric oscilla…
Generation of a time-bin Greenberger--Horne--Zeilinger state with an optical switch
Hsin-Pin Lo, Takuya Ikuta, Koji Azuma +3
Multipartite entanglement is a critical resource in quantum information processing that exhibits much richer phenomenon and stronger correlations than in bipartite systems. This ad…
