Error Mitigation by Zero-Noise Extrapolation (ZNE) in Indirect-Control System
Arijit Das, Masaki Owari
The indirect-control paradigm offers a scalable approach to quantum computation by restricting external operations to a small subset of qubits, whereas the entire system evolves un…
Multicast quantum network coding as optimal symmetric universal cloning over a quantum network
Go Kato, Mio Murao, Masaki Owari
We study the problem of perfectly multicasting symmetric universal clones of unknown quantum states over quantum networks with free classical communication. We construct a protocol…
Analysis of Regional Disparities of Location of Sports Facilities and Sports Education Using Scientific Satellite Data
Shoichi Otomo
This manuscript is an English translation and extended version of a paper originally published in Japanese (Otomo, 2024). With the advancement of information and communication tech…
Direct Imaging of Temperature Evolution of Polar Nanoregions and Chemically Ordered Regions in PMN Relaxor: Evidence for Polar Phase Percolation
Kohei Hino, Daisuke Morikawa, Desheng Fu +2
Polar nanoregions (PNRs) are central to understanding the exceptional dielectric and piezoelectric properties of relaxor ferroelectrics and are key to advancing dielectrics for hig…
BCS-BEC crossover driven by small Fermi pockets of a high-Tc cuprate superconductor
Junhyeok Jeong, Yamato Enomoto, Yoshimitsu Kohama +16
Fermi arcs observed in underdoped cuprates have sparked debate over whether they represent segments of a large Fermi surface or small Fermi pockets. This ambiguity has long hindere…
Description of curved spacetimes by finite-size matrices in the type IIB matrix model
Keiichiro Hattori, Tatsuya Seko, Asato Tsuchiya
The type IIB matrix model is expected to give a nonperturbative formulation of superstring theory. Its covariant derivative interpretation provides a method to describe curved spac…
