Millions of atoms entangled in record-breaking quantum tests
Two teams report pushing the spooky effect to larger scales than ever before
In a feat of quantum one-upmanship, two teams of scientists have staked new claims of linking whopping numbers of atoms at the quantum level.
Researchers from Geneva demonstrated quantum entanglement of 16 million atoms, smashing the previous record of about 3,000 entangled atoms (SN Online: 3/25/2015). Meanwhile, scientists from Canada and the United States used a similar technique to entangle over 200 groups of a billion atoms each. The teams published their results online March 14 in a pair of papers posted at arXiv.org.
