Rydberg Atom-Based Sensors: Principles, Recent Advances, and Applications

Photonics
Rydberg atoms are neutral atoms excited to high principal quantum number states, which endows them with exaggerated properties such as large electric dipole moments, long lifetimes, and extreme sensitivity to external electromagnetic fields.

Rydberg-atom Quantum Simulator Development [PDF]

, 2018
KAIST 2018 대표 연구성과 10선양자컴퓨팅이 중요한 미래기술의 하나로 대두되고 있다. 최근 KAIST의 물리학 연구진들이 초기 단계의 양자컴퓨팅에 해당하는 리드버그 원자를 이용한 25큐빗 양자 시뮬레이터를 실험-이론의 공동연구를 통하여 개발하였다. 이 양자시뮬레이터는 양자-아이징모델로 잘 알려진 중요한 물리문제를 계산하는 데 활용되어, 양자얽힘 다체계의 열화과정을 실험적으로 관찰하는데 성공하였다. 이 시스템은 프로그램이 가능한 범용 양자컴퓨터

Ultracold long-range van der Waals Rydberg trimers

Communications Physics
Rydberg molecules are an essential ingredient of cold molecular sciences. Due to the richness of interactions between Rydberg atoms and neutral atoms, new kinds of Rydberg molecules and binding mechanisms are still to be discovered.

Non-Elastic Processes in Atom Rydberg-Atom Collisions: Review of State of Art and Problems

, 2015
International audienceIn our previous research, it has been demonstrated that inelastic processes in atom Rydberg-atom collisions, such as chemi-ionization and ( n- n') mixing, should be considered together.
