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…
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…
Collective biphoton temporal waveform of photon-pair generated from Doppler-broadened atomic ensemble
Heewoo Kim, Hansol Jeong, Han Seb Moon
Photonic quantum states generated from atomic ensembles will play important roles in future quantum networks and long-distance quantum communication because their advantages, such…
