Near-Unitary Spin Squeezing in Yb
Boris Braverman, Akio Kawasaki, Edwin Pedrozo-Peñafiel +9
Spin squeezing can improve atomic precision measurements beyond the standard quantum limit (SQL), and unitary spin squeezing is essential for improving atomic clocks. We report sub…
Sub-Hertz resonance by weak measurement
Weizhi Qu, Jian Sun, Shenchao Jin +3
Weak measurement (WM) with state pre- and post-selection can amplify otherwise undetectable small signals and thus promise great potentials in precision measurements. Although freq…
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…
Coherence assisted resonance with sub-lifetime-limited linewidth
Feng Lei, Pengxiong Li, Liang Jiang +2
We demonstrate a novel approach to obtain resonance linewidth below that limited by coherence lifetime. Cross correlation between induced intensity modulation of two lasers couplin…
