The term “quantum supremacy” refers to the point at which a quantum computer can perform a task that is beyond the practical capabilities of even the most advanced classical supercomputers. John ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not ...

Imagine the tiniest game of checkers in the world—one played by using lasers to precisely shuffle around ions across a very small grid.

Quantum computers, which process information leveraging quantum mechanical effects, have the potential to outperform classical computers in some optimization and computational tasks. In addition ...
