IENGF参量下转换实验中量子力学和量子信息基础的最新实验进展
Review of recent experimental progresses in Foundations of Quantum Mechanics and Quantum Information obtained in Parametric Down Conversion Experiments at IENGF
摘要：
本文综述了IENGF量子光学实验室“Carlo Novero”在量子力学和量子信息基础方面的一些最新实验进展。更详细地说，在简短介绍了我们的偏振纠缠光子源（基于两个I型PDC发射的精确叠加）和用它获得的结果之后，我们描述了一个创新的双缝实验，其中两个由PDC产生的简并光子分别被发送到一个特定的狭缝。除了代表干涉的可见性和“welcher weg”知识之间的关系的一个有趣的例子，这种配置已被建议用于测试德布罗意-玻姆理论对标准量子力学。我们的结果完全符合SQM的结果，但不同意dBB的预测。然后，我们讨论了最近的一个实验，以澄清的问题，哪些波粒观测值是真正考虑在讨论波粒二象性。该实验实现了Agarwal等人的理论建议，克服了以前实验的局限性。最后，我们提出了一个高强度高光谱选择PDC源的实现，用于量子信息的研究。
英文摘要：
We review some recent experimental progresses concerning Foundations of Quantum Mechanics and Quantum Information obtained in Quantum Optics Laboratory "Carlo Novero" at IENGF. More in details, after a short presentation of our polarization entangled photons source (based on precise superposition of two Type I PDC emission) and of the results obtained with it, we describe an innovative double slit experiment where two degenerate photons produced by PDC are sent each to a specific slit. Beyond representing an interesting example of relation between visibility of interference and "welcher weg" knowledge, this configuration has been suggested for testing de Broglie-Bohm theory against Standard Quantum Mechanics. Our results perfectly fit SQM results, but disagree with dBB predictions. Then, we discuss a recent experiment addressed to clarify the issue of which wave-particle observables are really to be considered when discussing wave particle duality. This experiments realises the Agarwal et al. theoretical proposal, overcoming limitations of a former experiment. Finally, we hint to the realization of a high-intensity high-spectral-selected PDC source to be used for quantum information studies.
