Spectral design principles for local-excitation retention in impurity-assisted atomic arrays
Junpei Oba
Enhanced local-excitation retention in atomic arrays allows to exploit cooperative radiative effects to suppress emission and prolong excited-state lifetimes. We consider an impuri…
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…
Inverse design of dual-band valley-Hall topological photonic crystals with arbitrary pseudospin states
Yuki Sato, Shrinathan Esaki Muthu Pandara Kone, Junpei Oba +1
Valley photonic crystals (VPCs) offer topological kink states that ensure robust, unidirectional, and backscattering-immune light propagation. The design of VPCs is typically based…
Fast simulation for multi-photon, atomic-ensemble quantum model of linear optical systems addressing the curse of dimensionality
Junpei Oba, Seiji Kajita, Akihito Soeda
Photons are elementary particles of light in quantum mechanics, whose dynamics can be difficult to gain detailed insights, especially in complex systems. Simulation is a promising…
