Quantum error correction provides the foundation for reliable quantum technologies, but the design of an error-correcting code depends strongly on the physical platform. Which quantum codes are best suited for communication? How should quantum codes be designed for distributed quantum networks? Can application-specific codes reduce the resources required for practical implementations?

Our research explores how the requirements of quantum communication and quantum networks can guide the design of quantum error-correcting methods. We are particularly interested in connecting quantum error correction with multipartite entanglement, graph states, higher-dimensional quantum systems, and photonic quantum technologies.

Research topics:

  • Quantum codes for communication and networks — Investigating how communication tasks and network architectures can guide the design of quantum error-correcting codes. We also investigate methods that reduce resource requirements while maintaining reliable protection against realistic noise.
  • Graph-state quantum codes — Constructing quantum codes from multipartite entangled states and stabilizer structures.
  • Higher-dimensional quantum codes — Exploring quantum error correction beyond qubits using qudit encodings.
  • Gottesman–Kitaev–Preskill (GKP) codes — Studying continuous-variable and hybrid approaches to fault-tolerant quantum information processing and communication.
  • Hybrid coding architectures — Combining discrete- and continuous-variable encodings, concatenated codes, and multi-layer coding for future quantum technologies.
