Long-Distance Entanglement

摘要

In August 2008, Daniel Salart et al. published the results of an experiment claiming a photon pair demonstrated quantum entanglement over a distance of 18km. This rocked the scientific establishment, as the bulk of academicians embrace the notion that momentum cannot be transferred from one visible surface to another without direct contact, space-time warping, or the emission and absorption or reflection of messenger particles. Erwin Schrodinger, who introduced the concept of quantum entanglement, proposed it only acted over very small distances.
