USTC IonQNet Group is the trapped-ion quantum information group at the University of Science and Technology of China.
Our research builds on the long coherence times and high-fidelity quantum control of trapped ions. We study quantum logic gates and phonon control driven by tightly focused light, develop microcavity-based photonic interfaces that combine high efficiency with high bandwidth, and build hybrid quantum networks connecting different physical systems.
Our goal is to bring quantum networks and distributed quantum computing into practical use.
Trapped-ion quantum computing node
From low-crosstalk dual-sided addressing to single-sided Magnus gates, with wavefront correction, axial modes and optical-tweezer phonon control.
Quantum network with cavity QED
Developing high-bandwidth, high-efficiency ion–photon interfaces through fiber microcavity fabrication, mode matching, metal shielding, and stable cavity control.
Hybrid quantum network
Building on long ion coherence and high-fidelity control to connect solid-state memories, develop neutral-atom interfaces and enable distributed quantum computing across physical systems.
