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…
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…
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…
