High-fidelity entanglement of polar molecules by dynamic geometric control

Scarlett S. Yu, Avikar Periwal, Jiaqi You +6

In quantum information systems made of optical tweezer arrays of ultracold molecules, thermal motion of molecules degrades the coherence of their interactions, which limits entangl…

Spectroscopy of the $X^{2} Σ^{+} (v = 2) \to A^{2} Π_{1/2} (v = 1)$ Transition in MgF: Hyperfine Structures and Spectroscopic Constants

Youngju Cho, Yongwoong Lee, Kikyeong Kwon +3

We report spectroscopic results of the $X^2Σ^+(v=2) \rightarrow A^2Π_{1/2}(v=1)$ transition in magnesium monofluoride (MgF). Using Doppler-free Laser-Induced Fluorescence (LIF) s…
