Magnetic graphs for cavity quantum electrodynamics
Sunkyu Yu, Xianji Piao, Namkyoo Park
Strengthening light-matter coupling has become a central challenge in cavity quantum electrodynamics (QED), enabling ultrafast gate operations, qubit protection, and deterministic…
Mapping open quantum dynamics onto graphs
Kyuho Kim, Dayeong Lee, Seungkyun Park +3
Graph-theoretic frameworks have been widely employed in quantum physics to address the high-dimensional complexity of quantum systems. Although open quantum dynamics incorporates s…
Multi-objective design of photon blockade for bright single-photon sources
Sunkyu Yu, Xianji Piao, Namkyoo Park
High-quality single-photon sources, realized through saturable emitters, photon blockade, or heralded pair generation, are indispensable building blocks for photonic quantum platfo…
Heavy-tailed open quantum systems reveal long-lived and ultrasensitive coherence
Sunkyu Yu, Xianji Piao, Namkyoo Park
Understanding random open quantum systems is critical for characterizing the performance of large-scale quantum devices and exploring macroscopic quantum phenomena. Various feature…
