摘 要: | Entanglement purificationholds the promise for quan-tum communication overlarge distances. Now Pan Jianwei (J.W. Pan), a CAS scholar working atthe University of Vienna, and hiscolleagues have obtained the firstever experimental verification of pu-rification of entangled quantumstates. Scientists believe their workcould be an important step towardslong-distance quantumcommunication.Distribution of entangled statesbetween distant locations is essen-tial for quantum communication overlarge di…
