量子物体天生具有对偶性吗?
Are Quantum Objects Born with Duality?
摘要:
我们首次通过探索量子物体的源效应来研究波粒二象性。具体分析了一对非局域纠缠二能级原子发射的单光子。令人惊讶的是,二元性被发现是一个有条件的现象,取决于光子的原子源。它可以通过原子态纯度通过一个精确的二次关系(可以称为对偶勾股定理)调谐到最大值、中等值甚至最小值(完全不存在)。分析显示了一种新的方式来调查对偶性会计如何创建单个量子对象。这一结果对波粒二象性的完备性有了新的认识,并可在各种实际物理系统中得到检验。
英文摘要:
We study wave-particle duality by exploring for the first time effects of a quantum object's source. A single photon emitted from a pair of nonlocally entangled two-level atoms is specifically analyzed. Surprisingly, duality is found to be a conditional phenomenon depending on the photon's atomic source. It can be tuned maximum, medium, and even minimum (completely absent) by the atomic state purity through an exact quadratic relation that can be called Duality Pythagorean Theorem. The analysis shows a new way of investigating duality by accounting how the single quantum object is created. The result sheds a new light on the fundamental understanding of the completeness of wave-particle duality, and can be tested in various practical physical systems.
