Non-perturbative CPMG scaling and qutrit-driven breakdown under compiled superconducting-qubit control: a single-qubit study
Jun Ye
Decoherence in superconducting qubits arises from both multilevel dynamics and structured environmental noise, yet perturbative models cannot capture all resulting signatures. Here…
Tensor Network Framework for Forecasting Nonlinear and Chaotic Dynamics
Jia-Bin You, Jian Feng Kong, Jun Ye
We present a tensor network model (TNM) for forecasting nonlinear and chaotic dynamics, bridging quantum many-body methods with classical complex systems. The TNM leverages hierarc…
Generation and optimization of entanglement between atoms chirally coupled to spin cavities
Jia-Bin You, Jian Feng Kong, Davit Aghamalyan +5
We explore the generation and optimization of entanglement between atoms chirally coupled to finite 1D spin chains, functioning as {\it spin cavities}. By diagonalizing the spin ca…
Exploring variational quantum eigensolver ansatzes for the long-range XY model
Jia-Bin You, Dax Enshan Koh, Jian Feng Kong +3
Finding the ground state energy and wavefunction of a quantum many-body system is a key problem in quantum physics and chemistry. We study this problem for the long-range XY model…
