Heralded entanglement between widely separated
atoms
Entanglement is the essential feature of quantum mechanics. Remarkably, ob-
servers of two or more entangled particles will find correlations in their mea-
surement results, that can not be explained by classical statistics. To make it a
useful resource, particularly for scalable long-distancequantum communica-
tion, the heralded generation of entanglement between distant massive quan-
tum 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.
