Channel concentration of critical quantum geometry
Qian-Rui Lee, Daw-Wei Wang
The quantum metric quantifies the total ground-state response along a parameter direction, but does not resolve how excitations share that response. We define channel concentration…

Efficient identification of critical regions via Flow Matching-based Monte Carlo initialization
Qian-Rui Lee, Daw-Wei Wang
Markov chain Monte Carlo (MCMC) is a standard tool for studying many-body systems, but its practical cost can become substantial, especially when simulations must be repeated acros…

Automatic Characterization of Fluxonium Superconducting Qubits Parameters with Deep Transfer Learning
Huan-Hsuan Kung, Chen-Yu Liu, Qian-Rui Lee +5
Accurate determination of qubit parameters is critical for the successful implementation of quantum information and computation applications. In solid state systems, the parameters…
