Navigating entanglement via Ruderman-Kittel-Kasuya-Yosida exchange: Snake, bouncing, boundary-residing, pulse, and damping-stabilized time-frozen trajectories
Son-Hsien Chen, Seng Ghee Tan, Ching-Ray Chang
Entanglement dynamics are fundamental to quantum technologies, yet navigating their temporal profiles (trajectories) remains challenging. Here, we propose a scalable solid-state pl…

Measuring the non-Abelian Quantum Phase with the Algorithm of Quantum Phase Estimation
Seng Ghee Tan, Son-Hsien Chen, Ying-Cheng Yang +3
We propose an approach to measure the quantum phase of an electron in a non-Abelian system using the algorithm of Quantum Phase Estimation (QPE). The discrete-path systems were pre…

General recipe for immediate entanglement death-birth transitions via Bell states: environmental Heisenberg exchange as an example
Son-Hsien Chen, Seng Ghee Tan, Che-Chun Huang
Environment is known to play a dual role in both extinguishing and establishing entanglement, leading to entanglement sudden death (ESD) and entanglement sudden birth (ESB). In thi…
