Abstract
The effect of environment-assisted measurement and quantum measurement reversal on the entanglement transfer in two parallel Heisenberg spin chains is investigated. We derive the exact analytical expression of the optimal final restoration, show that the distribution entanglement could be restored to the initial value, which is independent of the size of the spin chain. Comparing with the results obtained by the method of weak measurement, our results show notable superiorities on restoration scope and success probability.
