Quantum Fisher Information as the Speed Limit for Multipartite Entanglement
Zain H. Saleem, Da-Wei Luo, Anjala M. Babu +3
We derive a universal upper bound on the speed of multipartite entanglement generation. For arbitrary differentiable pure multipartite states undergoing parameter-dependent evoluti…

Two-qubit charger-battery system subject to weak, continuous measurements with quantum point contacts
Banumathy Manickam, Anil Shaji
Quantum batteries modeled as two-qubit systems coupled to Markovian thermal reservoirs have been shown to benefit from measurement-assisted charging, where projective measurements…
