Entanglement Criterion of N-Qubit State
Entanglement Criterion of N-Qubit State
摘要
In this paper, we shall develop a generic scheme to construct the criterion that an N-qubit state has true N-particle entanglement. For the N = 3 case, we show that violation of the Mermin's inequality │ E^LHV (σ^ x× σ^ y× σ^y + σ^y × σ^x×σ^y + σ^y ×σ^y× σ^x& -σ^x × σ^x ×σ^x)│≤2, is sufficient to confirm three-particle entanglement.
