Exact No Signaling in Time without Temporal Classicality
Minsu Kim, Jeongho Bang, Han Seb Moon
No signaling in time (NSIT) has often been treated as the clean operational remnant of noninvasive measurability. If an earlier measurement leaves every later marginal unchanged, t…
Photon shot-noise-limited Rydberg-EIT electrometry
Gyeongmin Ju, Ye Jin Yu, Heewoo Kim +4
Rydberg-atom electrometry is a core technique in the development of highly sensitive quantum electric-field sensors. Its sensitivity based on atom-photon interaction is typically l…
Atomic-referenced Hz-linewidth lasers via fiber interferometric stabilization
Changmin Ahn, Hansol Jeong, Seoyeon Yang +4
Narrow-linewidth lasers with absolute frequency anchoring are essential for precision metrology, coherent sensing, and emerging quantum technologies beyond laboratory environments.…
Superradiance of entangled photon pairs from a high-density chip-scale Cs vapor cell
Heewoo Kim, Bojeong Seo, Han Seb Moon
Superradiance is one of the most fundamental collective quantum phenomena in light-matter interactions and has been studied extensively since Dicke's seminal work. However, its pra…
