摘　　要：We consider generating maximally entangled states(Bell states)between two qubits coupled to a common bosonic mode,based on f-STIRAP.Utilizing the systematic approach developed by Wang et al(2017 New J.Phys.19093016),we quantify the effects of non-adiabatic leakage and system dissipation on the entanglement generation,and optimize the entanglement by balancing non-adiabatic leakage and system dissipation.We find the analytical expressions of the optimal coupling profile,the operation time,and the maximal entanglement.Our findings have broad applications in quantum state engineering,especially in solid-state devices where dissipative effects cannot be neglected.
