Abstract
We investigate the temporal evolution of entanglement of three spin qubits coupled to an XY spin-chain with Dzyaloshinsky–Moriya (DM) interaction environment. For an initial state with W, we find that the DM interaction can enhance slightly the decay of entanglement both in the weak coupling region and strong coupling one. However, for an initial state with GHZ, the decay of entanglement is very sensitive to the DM interaction in the strong coupling region.
