AI is the technology trend of the moment—but what’s 10 years down the road? Some experts say quantum computing will be the next game-changer. WSJ visited IBM’s quantum computing lab to learn why.

Scientists in the U.K. have successfully connected two separate quantum processors, paving the way for a quantum internet and, potentially, quantum supercomputers. Increasing the number of quantum ...

For decades, physicists have dreamed of a quantum internet: a planetary web of ultrasecure communications and super-powered computation built not from electrical signals, but from the ghostly ...

Here, the team led by Lidar used an algorithm they modified for the quantum computer to solve a variation of "Simon's problem," an early example of quantum algorithms that can, in theory, solve a task ...
