Lyapunov Control of Quantum Systems Based on Energy-Level Connectivity Graphs

2018 · IEEE Transactions on Control Systems Technology

This paper proposes a new multilayer Lyapunov control scheme based on energy-level connectivity graphs of quantum systems, which enables a high-probability population transfer to any eigenstate in high-dimensional quantum systems. We provide a graph connectivity …

Real-time parameter estimation for two-qubit systems based on hybrid control

2024 · Physical Review A

In this paper, we consider the real-time parameter estimation problem for a ZZ-coupled system composed of two qubits in the presence of spontaneous emission. To enhance the estimation precision of the coupling coefficient, we first …
