PT对称Bell态的经典纠缠与CPT纠缠
Classical Entanglement and CPT Entanglement of PT Symmetric Bell States
摘要
Abstract
We studied the classical entanglement problem of four parity-time (PT ) symmetric Bell states under Hermitian conditions .The results show that among the four PT symmetric Bell states ,|Φ-> and |Ψ-> are still classical quantum states , and are still maximally entangled states under Hermitian inner product ;whereas |Φ+> and |Ψ+>are no longer always classical quantum states ,and the classical quantum states normalized by Hermitian inner product are no longer always maximally entangled states under Hermitian inner product .关键词
