摘要
爱因斯坦-波多尔斯基-罗森(EPR)悖论凸显了量子力学缺乏局部现实的解释,并表明局部隐态模型与量子理论不相容。对于 N 量子位态,或更重要的 N 量子位混合态,我们以矛盾相等 "2=1 "的形式提出了 EPR 转向悖论。我们证明,只要同时满足 "纯态要求 "和 "测量要求",这个矛盾对于任何 N 量子比特态都成立。这也表明,EPR转向悖论存在于更普遍的情况中。最后,我们给出了具体的例子来证明和分析我们的论点。
Einstein–Podolsky–Rosen steering paradox “2=1” for N qubits
Einstein–Podolsky–Rosen (EPR) paradox highlights the absence of a local realistic explanation for quantum mechanics, and shows the incompatibility of the local-hidden-state models with quantum theory. For N-qubit states, or more importantly, the N-qubit mixed states, we present the EPR steering paradox in the form of the contradictory equality “”. We show that the contradiction holds for any N-qubit state as long as both “the pure state requirement” and “the measurement requirement” are satisfied. This also indicates that the EPR steering paradox exists in more general cases. Finally, we give specific examples to demonstrate and analyze our arguments.
