Research Overview

Our research focuses on the theoretical foundations of quantum computing, with particular emphasis on superconducting quantum circuits and their applications. We combine analytical methods with numerical simulations to understand and optimize quantum gate operations, decoherence processes, and error correction.

Theoretical Methods

  • Circuit quantization and Hamiltonian analysis
  • Master equation approaches for open quantum systems
  • Perturbation theory and effective Hamiltonian methods
  • Numerical diagonalization and time evolution

Current Projects

  • Fluxonium qubit systems, 2-qbt gates, and scaling up fluxonium systems
  • Quantum error correction of superconducting qubits
  • Novel solid-state-based qubit theory
