Scientists don’t fully understand quantum entanglement—but they know that space, or physical distance, is not a factor in the “communication” between two entangled particles. If one is affected by a force or a measurement, the other also reacts in the same moment, even if they are separated by leagues. Unlocking the secrets of this phenomenon could lead to incredible advancements in technology, such as quantum machines that transmit information faster than light.
Quantum Entanglement Could Stretch Across Time 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.
