Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

Researchers have developed a chip-based quantum random number generator that provides high-speed, high-quality operation on a miniaturized platform. This advance could help move quantum random number ...

In superconducting materials, pairs of electrons form a shared quantum-mechanical state. Control of this macroscopic quantum state is a key feature that is required for superconducting quantum ...
