Query: Entanglement generation between unstable optically active qubits without
  photodetectors   We propose a robust deterministic scheme to generate entanglement at high
fidelity without the need of 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 holds potential to solve entanglement generation problems, e.g., in
distributed quantum computing.
