摘要：
We propose theoretical schemes to generate n-electron GHZ state, n-electron cluster state, and four-electron |chi > state by using quantum-dot spins in double-sided optical microcavities. With single-photon detection and local unitary operations, these entangled states could be deterministically generated. The fidelities of our schemes are also calculated, which illustrate that our schemes have high performance under appropriate parameter conditions.
