Efficient quantum memory for heralded single photons generated by cavity-enhanced spontaneous parametric downconversion
Yu-Chih Tseng, Yan-Cheng Wei, Ying-Cheng Chen
We interface a spontaneous parametric down conversion (SPDC) crystal and a cold atomic ensemble and demonstrate a highly efficient quantum memory through polarization-encoded singl…
A Weakly-Interacting Many-Body System of Rydberg Polaritons Based on Electromagnetically Induced Transparency
Bongjune Kim, Ko-Tang Chen, Shih-Si Hsiao +9
We proposed utilizing a medium with a high optical depth (OD) and a Rydberg state of low principal quantum number, , to create a weakly-interacting many-body system of Rydberg p…
Broadband coherent optical memory based on electromagnetically induced transparency
Yan-Cheng Wei, Bo-Han Wu, Ya-Fen Hsiao +2
Quantum memories, devices that can store and retrieve photonic quantum states on demand, are essential components for scalable quantum technologies. It is desirable to push the mem…
Memory-based optical polarization conversion in a double-Λ atomic system with degenerate Zeeman states
Yan-Cheng Wei, Sheng-Xiang Lin, Pin-Ju Tsai +1
Optical memory based on electromagnetically induced transparency (EIT) in a double-Λatomic system provides a convenient way to convert the frequency, bandwidth or polarization of o…
Raman Gray Molasses Cooling of Cesium Atoms on the D2 Line
Ya-Fen Hsiao, Yu-Ju Lin, Ying-Cheng Chen
We present a systematic study on the Raman gray molasses cooling (RGMC) of cesium atoms on the transition. Due to the large splitting in the excited hyperfine transitions of…
Spectroscopic determination of the s-wave scattering lengths of 86Sr and 88Sr
P. G. Mickelson, Y. N. Martinez, A. D. Saenz +5
We report the use of photoassociative spectroscopy to determine the ground state s-wave scattering lengths for the main bosonic isotopes of strontium, 86Sr and 88Sr. Photoassociati…
