  In this paper we study the influence of Dzyaloshinskii-Moriya (DM)
interaction on quantum correlations in two qubit Werner states and maximally
entangled mixed states (MEMS). We consider our system as a closed system of a
qubits pair and one auxiliary qubit which interact with any one of the qubit of
the pair through DM interaction. We show that DM interaction, taken along any
direction (x or y or z), does not affect two qubit Werner states. On the other
hand the MEMS are affected by x and z components of DM interaction and remain
unaffected by the y component. Further, we find that the state (i.e probability
amplitude) of auxiliary qubit do not affect the quantum correlations in both
the states, only DM interaction strength influences the quantum correlations.
So one can avoid the intention to prepare the specific state of auxiliary qubit
to manipulate the quantum correlations in both the states. We mention here that
avoiding the preparation of state can contribute to cost reduction in quantum
information processing. We also observe the phenomenon of entanglement sudden
death in the present study.
