论文摘要
大自然允许人们探索一系列显着的量子效应。最突出的是,可以在多个粒子系统,多个量化场和混合组合中观察到量子纠缠。然而,这种多样性也导致了关于在任何给定的物理场景中真正构成纠缠的真正构成的结论矛盾的。通过明确允许各种观点,我们严格考虑在第一个和第二个量化的背景下考虑不同的纠缠概念。通过提供启发性的例子,我们表明粒子的纠缠和野外纠缠实际上是可能发生并彼此独立观察的不同现象。这个结论不仅影响了我们的基本理解,而且对量子技术具有直接的影响,这些技术可以利用在实际情况下利用那些独立的纠缠形式。
Nature allows one to explore a manifold of remarkable quantum effects. Most prominently, quantum entanglement can be observed in many-particle systems, between multiple quantized fields, and in hybrid combinations thereof. This diversity, however, also leads to contradicting conclusions about what truly constitutes entanglement in any given physical scenario. By explicitly allowing various perspectives, we rigorously consider different notions of entanglement in the context of first and second quantization. By providing instructive examples, we show that particle entanglement and field entanglement are actually distinct phenomena that can occur and be observed independently of each other. This conclusion not only affects our fundamental understanding but has direct implications for quantum technology which can harness those independent forms of entanglement in practical scenarios.
