From Santa Barbara, CA, to Hefei, China, scientists are developing a new kind of computer that will make today's machines look like toys.
Harnessing the mysterious powers of quantum mechanics, the technology will perform tasks in minutes that even supercomputers could not complete in thousands of years. In the fall of 2019, Google unveiled an experimental quantum computer showing this was possible. Two years later, a lab in China did much the same.
But quantum computing will not reach its potential without help from another technological breakthrough. Call it a "quantum internet" — a computer network that can send quantum information between distant machines.
At the Delft University of Technology in the Netherlands, a team of physicists has taken a significant step toward this computer network of the future, using a technique called quantum teleportation to send data across three physical locations. Previously, this was possible with only two.
