Abstract We propose an efficient multi-particle entanglement generation protocol using a quantum dot and optical micro-cavity coupled system. Multi-electron spins may become entangled by the interaction between the electrons and the single photons. The entanglement success probability relies on the coupling strength and the cavity leakage, which is also discussed.
