Quantum Entanglement Could Cross Time
Lisa Grossman, Wired
In the weird world of quantum physics, two linked particles can share a single fate, even when they’re miles apart.
Now, two physicists have mathematically described how this spooky effect, called entanglement, could also bind particles across time.
If their proposal can be tested, it could help process information in quantum computers and test physicists’ basic understanding of the universe.
“You can send your quantum state into the future without traversing the middle time,” said quantum physicist S. Jay Olson of Australia’s University of Queensland, lead author of the new study.
