Long-distance quantum information exchange -- success at the nanoscale

At the Niels Bohr Institute, University of Copenhagen, researchers have realized the swap of electron spins between distant quantum dots. The discovery is a step towards applications of quantum information, as the dots leave enough room for delicate control electrodes, enabling integration with traditional microelectronics and perhaps, a future quantum computer. The result is achieved via collaboration with Purdue University and the University of Sydney, Australia, now published in Nature Communications.
