Over the past century, scientists have made huge strides in understanding the mind-bending rules that govern the microworld of atoms and subatomic particles. But these rules, called quantum mechanics<\/a>, contain one particularly bizarre, unexplained phenomenon: quantum entanglement<\/a>.<\/p>\n\n\n\n

Imagine two subatomic particles that mirror changes in each other instantaneously over any distance \u2013 apparently without communicating. Einstein<\/a> called it \u201cspooky action at a distance\u201d and although no one can explain how it works, scientists have already begun to harness its power.<\/p>\n\n\n\n

So-called quantum computing could give rise to computers that can shatter existing data encryption in minutes \u2013 and use the laws of physics to create a totally secure, unhackable network. But even as researchers are poised to transform the digital world with entanglement, a few doubts about it remain, and to rule them out will take a ground-breaking experiment.<\/p>\n\n\n\n

NOVA takes you to a frigid mountaintop in the Canary Islands where physicists will use massive telescopes to catch light from quasars<\/a> at opposite ends of the universe to control detectors in a record-breaking experiment that might settle the remaining questions once and for all. <\/p>\n\n\n\n
