This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a low-slung building in an office park near the southeastern edge of the San Francisco Bay,

Using a conventional computer and cutting-edge mathematical tools and code, physicists at the Center for Computational Quantum Physics (CCQ) at the Simons Foundation's Flatiron Institute and collaborators at Boston University have cracked a daunting quantum physics problem previously claimed to be solvable only by quantum computers.

The U.S. Department of Commerce will invest $2 billion into quantum chip foundries and startups as the "Q-Day" Bitcoin threat nears.

Quantum computing could lead to revolutions in cryptography, materials design and telecommunications. But fulfilling those promises could be many years away

IonQ is investing $100 million in an R&D facility in Boulder, which is expected to be completed in late summer.

The day when a quantum computer can crack commonly used forms of encryption is drawing closer. The world isn’t prepared, experts say.
