Abstract
We analyze the dynamics of entanglement and quantum discord in a two-qubit system coupled to squeezed reservoirs. We present analytical expressions that can be used to efficiently calculate the evolution of quantum discord and entanglement between the two qubits. Our results show that quantum discord is a more general and robust measure of quantum correlations than entanglement. Furthermore, there is a relationship between the time before sudden death of entanglement and the reservoir squeezing angle. Additionally, the increase of squeezing angle accelerates the decay of quantum discord. These results provide new avenues for controlling quantum correlations and designing quantum states that can be used for various quantum computing applications.
