Pin It

Einstein called it "spooky action at a distance."

That's because entanglement, a voodoo-like phenomenon in quantum physics linking particles that once interacted, seems to surpass the speed of light, violating the cosmic speed limit.

Because of this, it doesn't fit in with Einstein's theory of relativity, so he concluded that it was too ludicrous to be real.

But it is real, as physicists proved last year. And it's actually going to be pretty useful, whether for a form of computing that is exponentially faster than what we have now, the creation of unbreakable codes and a more secure internet, or even for solving problems in chemistry and developing new drugs and materials.

Now, quantum computing researchers at the Royal Melbourne Institute of Technology (RMIT) in Australia have gotten even better at detecting this spooky phenomenon, which has big implications for the future of entanglement.
