Long-range entanglement generation via frequent measurements
Lian-Ao Wu, Daniel A. Lidar, Sara Schneider · Physical Review A · 2004
A method is studied wherein two noninteracting quantum subsystems, that each interact with a third subsystem, are entangled via repeated projective measurements of the state of the third subsystem. A variety of condensed matter and quantum optical examples are presented. The method can be used to establish long range entanglement between distant parties in one parallel measurement step, thus obviating the need for entanglement swapping.
