Exact No Signaling in Time without Temporal Classicality
Minsu Kim, Jeongho Bang, Han Seb Moon
The paper demonstrates that exact no‑signaling‑in‑time (NSIT) does not guarantee a classical temporal description, by analytically solving common fixed points of nonselective measu…
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…
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.…
Quantum interference between autonomous dissimilar quantum light sources for hybrid quantum networks
Kyu-Young Kim, Heewoo Kim, Dong Hyun Park +6
Hybrid quantum systems play a crucial role in advancing scalable and versatile quantum networks as they combine the strengths of different quantum platforms. An important challenge…
Real-Field Hong-Ou-Mandel Interference of Indistinguishable Coherent Photons via Long Optical Injection-Locking over 50 km Fiber
Seoyeon Yang, Danbi Kim, Hansol Jeong +1
Measurement-device-independent quantum key distribution (MDI-QKD) has garnered significant attention for its potential to enable security-loophole-free quantum communication. Succe…
