Size-Reduction of Rydberg collective excited states in cold atomic system
Dong-Sheng Ding, Yi-Chen Yu, Zong-Kai Liu +2
The collective effect of large amounts of atoms exhibit an enhanced interaction between light and atoms. This holds great interest in quantum optics, and quantum information. When…
Epidemic spreading and herd immunity in a driven non-equilibrium system of strongly-interacting atoms
Dong-Sheng Ding, Zong-Kai Liu, Hannes Busche +4
It is increasingly important to understand the spatial dynamics of epidemics. While there are numerous mathematical models of epidemics, there is a scarcity of physical systems wit…
Synchronized resistance to inhomogeneous magnetic field-induced dephasing of an image stored in a cold atomic ensemble
Ying-Hao Ye, Lei Zeng, Yi-Chen Yu +8
Long-lived storage of arbitrary transverse multimodes is important for establishing a high-channel-capacity quantum network. Most of the pioneering works focused on atomic diffusio…
Experimental demonstration of Cavity-Free Optical Isolators and Optical Circulators
En-Ze Li, Dong-Sheng Ding, Yi-Chen Yu +9
Cavity-free optical nonreciprocity components, which have an inherent strong asymmetric interaction between the forward- and backward-propagation direction of the probe field, are…
Experimental demonstration of switching entangled photons based on the Rydberg blockade effect
Yi-Chen Yu, Ming-Xin Dong, Ying-Hao Ye +3
The long-range interaction between Rydberg-excited atoms endows a medium with large optical nonlinearity. Here, we demonstrate an optical switch to operate on a single photon from…
Temporal Wheeler's delayed-Choice Experiment based on Cold Atomic Quantum Memory
Ming-Xin Dong, Dong-Sheng Ding, Yi-Chen Yu +8
Nowadays the most intriguing features of wave particle complementarity of single photon is exemplified by the famous Wheeler's delayed choice experiment in linear optics, nuclear m…
