We propose a robust deterministic scheme to generate entanglement at high fidelity without the need for photodetectors even for quantum bits (qubits) with extremely poor optically active states. Our protocol employs stimulated Raman adiabatic passage for population transfer without actually exciting the system. Furthermore, it is found to be effective even if the environmental decoherence rate is of the same order of magnitude as the atom-photon coupling frequency. Our scheme has the potential to solve entanglement generation problems, e.g., in distributed quantum computing.
