Overview of Academic Research
Prof. Zhang’s research is focused on quantum memory and quantum network, he pushed the progresses on establishing long-distance, high-dimensional entanglement in cold atomic ensembles and single-atom systems.
His major achievements:
* In cold atomic ensembles, by utilizing the polarization and orbital angular momentum modes of photons and adopting the Raman storage protocol, high-bandwidth and multi-degree-of-freedom hyper-entangled quantum storage has been realized.
* In single-atom systems, entanglement between single-atom memories has been used to demonstrate the DIQKD protocol. With the aid of high-efficiency frequency converters, a single-atom network link over a 33-kilometer fiber distance and the distribution of atom-photon entanglement over 101 kilometers have been realized.
Research Directions/Fields:
* Long-distance, high-dimensional entanglement between cold atomic ensembles
* A Single-atom quantum network
