Anomaly fluctuation theorem for quantum coherence dynamics
Kun Zhang, Hai-Long Shi, Xiao-Hui Wang +1
Quantum coherence is a central resource in quantum information science, yet general frameworks and constraints governing its dynamics remain limited. Although quantum coherence lac…
Emergent mirror symmetry in the optimization of the central-spin quantum battery
Hui-Yu Yang, Kun Zhang, Xiao-Hui Wang +1
Quantum batteries provide a useful setting for exploring nonequilibrium many-body effects in energy storage. Here we investigate the optimization of a quantum battery based on the…
Palindromic structure of depth-efficient quantum search algorithms
Kun Zhang, Hai-Long Shi, Xiao-Hui Wang +1
Grover's algorithm is optimal in query complexity, but not necessarily in circuit depth. We formulate unstructured quantum search as a circuit-depth optimization problem and identi…
Global Bounds beyond Local Quantum Metrology
Hai-Long Shi, Augusto Smerzi
Quantum Cramér--Rao theory is intrinsically local: it bounds precision near a specified parameter value, and its saturating measurement generally depends on that value. Barankin-ty…
