关于量子力学的完备性

On the Completeness of Quantum Mechanics

Marian Kupczynski

摘要:

Accardi及其合作者报道的量子密码学、量子计算机计划、时空量子化计划以及最近的计算机实验表明了爱因斯坦70多年前开始的关于量子力学完备性讨论的重要性和现实性。许多年前我们就指出,违背贝尔不等式既不是量子力学完备性的证明,也不是违背爱因斯坦因果性的指示。我们还指出了如何以及在什么意义上的QM的完整性可能会测试的帮助下,统计非参数纯度检验。在本文中,我们回顾和完善我们的论点。我们还指出,量子力学的统计预测的两个粒子的相关实验不给任何确定性的预测,为一个单一的对。光束分离后,我们得到两个光束在相反的方向上移动。如果报告符合,则仅在射束与相应的测量装置相互作用并且检测到两个粒子之后。这一事实对量子密码学有影响。也就是说,由于缺乏严格的反相关性,Bob对波束执行的一系列测量并转换成比特串(密钥)通常与Alice使用相同过程找到的密钥不同。

英文摘要:

Quantum cryptography, quantum computer project, space-time quantization program and recent computer experiments reported by Accardi and his collaborators show the importance and actuality of the discussion of the completeness of quantum mechanics (QM) started by Einstein more than 70 years ago. Many years ago we pointed out that the violation of Bell's inequalities is neither a proof of completeness of QM nor an indication of the violation of Einsteinian causality. We also indicated how and in what sense a completeness of QM might be tested with the help of statistical nonparametric purity tests. In this paper we review and refine our arguments. We also point out that the statistical predictions of QM for two-particle correlation experiments do not give any deterministic prediction for a single pair. After beam is separated we obtain two beams moving in opposite directions. If the coincidence is reported it is only after the beams had interacted with corresponding measuring devices and two particles had been detected. This fact has implications for quantum cryptography. Namely a series of the measurements performed on the beam by Bob and converted into a string of bits (secret key) will in general differ, due to lack of strict anti-correlations, from a secret key found by Alice using the same procedure.
