Professor Seigo Tarucha, Professor Kazuhiko Hirakawa and their colleagues have succeeded in demonstrating nonlocal quantum entanglement in a solid for the first time. One entangled electron pair was extracted from an electron pair in a superconductor, separated into two spatially separated quantum dots, each in an entangled state, and then recombined in a different superconductor for detection and demonstration. This achievement brings us closer to the realization of entangled electron pair generators, which are needed for quantum computation. The paper was published in Nature Communications on 1 July (UK time).
