We theoretically investigate various quantum systems and explore applications of quantum information:

  • Quantum error correction to protect quantum information from decoherence.
  • Quantum information processing with superconducting circuits, NV centers in diamond, and various platforms.
  • Quantum transduction based on opto-electro-mechanical or opto-electro-magnonic systems
  • Quantum networks and secure quantum communication over long distances
  • Topological quantum systems robust against local perturbations
  • Exceptional point and parity-time (PT) symmetry
