广义类GHZ态的量子Fisher信息OA
Quantum Fisher Information of General GHZ-class State
研究了广义类GHZ态的量子Fisher信息。结果表明，量子Fisher信息的大小仅仅只由叠加系数决定，而与相对相位的大小无关。
We investigate the quantum Fisher information of general W-class state. It is shown that the quantum Fisher information is only dependent on the superposition coefficients and is independ-ent of the relative phase.
