Creation of 2000-atom Greenberger-Horne-Zeilinger states by entanglement amplification
Yajuan Zhao, Rui Zhang, Wenlan Chen +2
We propose a novel entanglement-creation scheme in a multi-atom ensemble, named entanglement amplification, which converts unentangled states into entangled states and amplifies le…
Geometrically asymmetric optical cavity for strong atom-photon coupling
Akio Kawasaki, Boris Braverman, Edwin Pedrozo-Peñafiel +11
Optical cavities are widely used to enhance the interaction between atoms and light. Typical designs using a geometrically symmetric structure in the near-concentric regime face a…
Creation of a Bose-condensed gas of rubidium 87 by laser cooling
Jiazhong Hu, Alban Urvoy, Zachary Vendeiro +3
We demonstrate direct laser cooling of a gas of rubidium 87 atoms to quantum degeneracy. The method does not involve evaporative cooling, is fast, and induces little atom loss. The…
An optical phase-locking with large and tunable frequency difference based on vertical-cavity surface-emitting laser
Wenlan Chen, Xianghui Qi, Lin Yi +2
We present a novel technique to phase-lock two lasers with controllable frequency difference. In our setup, one sideband of a current modulated Vertical-Cavity Surface-Emitting Las…
