The Olympics are over but international competition is still hot and records continue to fall. Just eight short days after a Chinese physics group posted a paper claiming to have achieved quantum teleportation across a record-setting 97 kilometers (just more than 60 miles), a joint Canadian/European team posted another claiming to have teleported a single photon across 143 kilometers (nearly 89 miles).

That second paper hasn’t been peer-reviewed yet (the Chinese paper just came out in the peer-reviewed journal Nature on August 9), but should it stand up to scrutiny, we’ve got yet another new distance record in the quantum teleportation event. Considering that just two years ago ten miles was the high bar, this is a space to watch.
