In this paper, the pairwise entanglement of two qubits in a system consists of a dissipative cavity with an arbitrary number of qubitsis investigated. To model the dissipation in this cavity, the Gardiner-Collett approach has been utilized.Theanalytical expression of the wave function of the system is obtainedby solving the time-dependent Schrodinger equation with the initial state as a superposition of single-excitation of two arbitrary qubits. Entanglement dynamics of any two qubitsfor different number of qubits and various coupling regimeshas been investigated.
