Research Statement

We are developing a quantum device with trapped ions for quantum information processing including quantum computation, quantum simulation and quantum metrology.

We have demonstrated the longest coherence time of a single qubit in the world, which was published to Nature Photonics 2017 and Nature Communications 2021.
We also have realized scalable global entangling gates on arbitrary ion-qubits, which was published to Nature 2019.
We have performed the experimental test of fundamental thermodynamic equality and showed the principle of thermodynamics can be extended to quantum regime, which was published Nature Physics 2015.
