| Summary: | This work proposes a method for stabilizing entanglement in Heisenberg spin dimers by optimizing time-varying magnetic fields. Unlike traditional approaches that rely on static configurations, the method adapts the magnetic field in real-time using simulated annealing, addressing oscillatory degradation of entanglement. This dynamic control approach aims to extend coherence times and improve the stability of high-concurrence states, offering a potentially more robust solution for quantum communication and computation. The approach complements existing findings by focusing on the longevity and coherence of entanglement, rather than its generation or distribution, providing an alternative to conventional fixed-field methods and contributing to the ongoing efforts to enhance entanglement stability in quantum systems. |
