Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems.

SEEQC, which traces its lineage back to IBM, is building the world’s quantum computers. They might prove critical in the ...

Quantum computing is moving from lab curiosity to practical tool far faster than most people realize, and the shift could reorder entire industries in a single decade. Instead of incremental gains, ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

Fully functional quantum computers remain out of reach, but optimism across the field is rising. At the Q2B Silicon Valley conference in December, researchers and executives ...

Quantum computers made from qubits based on extremely cold atoms have been getting larger at an impressive rate, which may soon make them computationally powerful – but errors arise at a rate that ...

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.
