Charging a quantum spin network towards Heisenberg-limited precision
We present a cooperative protocol to charge quantum spin networks up to the highest-
energy configuration, in terms of the network's magnetization. The charging protocol …

The effectiveness of a quantum battery relies on a robust charging process, yet these are
often sensitive to initial state of the battery. We introduce the concept of a universally …
