  • Entanglement is a key aspect of quantum mechanics, leading to unexpected correlations in measurement results that classical statistics can't explain.
  • To enable long-distance quantum communication, it's essential to create and analyze heralded entanglement between distant quantum systems.
  • This study demonstrates successful heralded entanglement between spins of two rubidium-87 atoms located 20 meters apart, highlighting its potential for quantum information science and testing quantum mechanics.

Article Abstract

Entanglement is the essential feature of quantum mechanics. Notably, observers of two or more entangled particles will find correlations in their measurement results that cannot be explained by classical statistics. To make it a useful resource, particularly for scalable long-distance quantum communication, the heralded generation of entanglement between distant massive quantum systems is necessary. We report on the creation and analysis of heralded entanglement between spins of two single rubidium-87 atoms trapped independently 20 meters apart. Our results illustrate the viability of an integral resource for quantum information science, as well as for fundamental tests of quantum mechanics.
