Abstract
We investigate entanglement in an open quantum system, specifically in bipartite and tripartite systems of two dimensions for weak and strong fields based on numerical calculations. We address a systematic approach in calculating a tripartite entanglement using concurrence as a measure of entanglement based on a direct detection scheme (quantum jump method - with and without knowledge of which qubit jumps). We are also numerically calculating entanglement using ‘Adiabatic Elimination’ and the ‘Three-way tangle’ or ‘Residual Entanglement’ approaches. We present significant differences of the concurrences of the various bipartite splits among the results of two ways of direct detection scheme and when a phase is introduced in the coupling term of the energy.
