Abstract
We will discuss the entanglement in a two-qubit systemdynamically generated by the interaction of the qubit system with itsenvironment (bath or reservoir). The interactions considered would beboth of the purely dephasing, no energy exchange, as well as dissipative, dephasing accompanied with dissipation.An introduction is provided tothe concept of entanglement as well as Open Quantum Systems. Sinceinteraction with the environment makes the system mixed, we discuss indetail the measure of entanglement called concurrence as well as arecently introduced description of mixed state entanglement usingprobability density function.
