论文摘要
量子相干性可以维持到星际距离。结果表明，电磁光谱的某些区域的光子平均自由路径（例如在无线电或X射线范围内）可以使光子的量子状态保持到银河系距离。因此，涉及量子纠缠的过程（例如量子传送）可以在银河系或其他星系中很长的距离内实现。这具有根本的兴趣，并在量子力学的角色方面提供了新的方向。讨论了该观察结果的一些有限的应用。
Quantum coherence could be sustained up to interstellar distances. It is shown that the photon mean free path in certain regions of the electromagnetic spectrum, such as within the radio or x-ray ranges, could allow sustaining of the quantum state of a photon up to galactic distances. Therefore processes involving quantum entanglement, such as quantum teleportation, could be realized over very long distances in the Milky Way or other galaxies. This is of fundamental interest and offers a new direction in the role of quantum mechanics. Some limited applications of this observation are discussed.
