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…
Kondo Screening of Local Moments in a Triangular Triple Quantum Dot Connected to Normal and Superconducting Leads
Masashi Hashimoto, Yoshimichi Teratani, Masaya Shirotani +5
We study the interplay between the Kondo and superconducting (SC) proximity effects, taking place in a triangular triple quantum dot (TTQD) connected to one normal and two SC leads…
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…
Observing a Phase Transition in a Coherent Ising Machine
Hiroki Takesue, Yasuhiro Yamada, Kensuke Inaba +8
A coherent Ising machine (CIM) is known to deliver the low-energy states of the Ising model. Here, we investigate how well the CIM simulates the thermodynamic properties of a two-d…
Detecting partial synchrony in a complex oscillatory network using pseudo-vortices
Yasuhiro Yamada, Kensuke Inaba
Partial synchronization is characteristic phase dynamics of coupled oscillators on various natural and artificial networks, which can remain undetected due to the complexity of the…
Thermodynamic quantities of two-dimensional Ising models obtained by noisy mean field annealing and coherent Ising machine
Kensuke Inaba, Yasuhiro Yamada, Hiroki Takesue
Noisy mean field annealing (NMFA) is an algorithm that mimics a coherent Ising machine (CIM), which is an optical system for solving Ising problems. The NMFA has reproduced the sol…
Experimental observation of chimera states in spiking neural networks based on degenerate optical parametric oscillators
Tumi Makinwa, Kensuke Inaba, Takahiro Inagaki +9
We experimentally demonstrate that networks of identical photonic spiking neurons based on coupled degenerate parametric oscillators can show various chimera states, in which, depe…
