Research

My research interests are in quantum information science, quantum physics and quantum technology including:

  • Entanglement and decoherence of quantum nanodevices such as quantum dots and superconducting qubits
  • Continuous quantum measurement and quantum feedback control
  • Entanglement and its applications in quantum metrology and precision detection technology
  • Quantum coherence dynamics of atomic, molecular and optical systems
  • Theoretical modeling and simulation of complex quantum systems
  • Non-Markovian quantum open systems and quantum trajectories
  • Quantum phase transition, topological order and quantum topological computation
  • Entanglement of many-body systems and quantum fields.
