Exact Entanglement-Depth Speed Frontier for Complete Quantum Charging
Wenlong Sun, Gang Lu, Yuanfeng Jin
Complete quantum charging provides a sharp setting in which to ask how much multipartite entanglement is forced by speed itself. For a closed \(N\)-qubit battery evolving from \(\k…

Pre-Channel Entanglement Shaping Achieves Fundamental Superiority over Post-Distillation: A Geometric Entropy Perspective
Gang Lyu, Wenlong Sun, Yuanfeng Jin +1
Traditional entanglement distillation follows a post-processing paradigm, a noisy quantum state, after full transmission through a noisy channel, is treated as a static resource to…
