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…
Weak value picture on quantum observables: gauge-invariant vector potentials
Sunkyu Yu, Xianji Piao, Namkyoo Park
The conservation of physical quantities under coordinate transformations, known as gauge invariance, has been the foundation of theoretical frameworks in both quantum and classical…
