非定域性与测量基的相关性

Nonlocality and the Correlation of Measurement Bases

Daegene Song

摘要:

纠缠所表现出的非定域性是量子理论最显著的特征之一。我们研究了纠缠量子比特的Bell型证明中的局域性假设,即一端量子比特的结果与另一端的基选择无关。最近有人声称,为了正确地纳入自我观察的现象,海森堡的时间倒退图像提供了一个一致的描述。我们表明,如果这一说法成立,假设在非局部性证明,在两端的基础选择是相互独立的可能不再是真的,并可能构成威胁的贝尔型证明的有效性。

英文摘要:

Nonlocal nature apparently shown in entanglement is one of the most striking features of quantum theory. We examine the locality assumption in Bell-type proofs for entangled qubits, i.e. the outcome of a qubit at one end is independent of the basis choice at the other end. It has recently been claimed that in order to properly incorporate the phenomenon of self-observation, the Heisenberg picture with time going backwards provides a consistent description. We show that, if this claim holds true, the assumption in nonlocality proofs that basis choices at two ends are independent of each other may no longer be true, and may pose a threat to the validity of Bell-type proofs.
