Abstract

We investigate the decoherence to generate quantum discord between two separable qubits of an unentangled mixed state and propose a series of feasible schemes to enhance quantum discord by means of reliable quantum operations. By combing our schemes with the previous proposal, one can note that the generated quantum discord can be greatly enhanced. Moreover, our success probability entirely depends on the quantum measurement strength.
