我们提出了一个定理，即三量子比特系统的所有广义Greenberger-Horne-Zeilinger态在概率上都违反Bell不等式。三量子比特系统的所有纯纠缠态都违反了贝尔不等式的概率;因此，人们有三个量子比特的吉辛定理。
We present a theorem that all generalized Greenberger-Horne-Zeilinger states of a three-qubit system violate a Bell inequality in terms of probabilities. All pure entangled states of a three-qubit system are shown to violate a Bell inequality for probabilities; thus, one has Gisin's theorem for three qubits.
