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.

This technology isn't ready to go mainstream yet, but getting portfolio exposure to it before that happens could prove a profitable strategy.

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