Quantum computing uses quantum mechanics—the physics governing particles at atomic and subatomic scales—to process information in totally different ways from today’s digital computers. Instead of ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the ...

Investors piled into quantum computing stocks in 2025, but many of them are now declining sharply.

Even as quantum computing advances steadily, it will not replace classical computers in the near future. Most current systems ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.
