New research suggests quantum computers capable of breaking internet encryption may arrive sooner than expected—with AI ...

What once took up the entire space of IBM’s early computer lab now fits on a chip. The question is how and when will the ...

Two research groups say they have significantly reduced the amount of qubits and time required to crack common online ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

Quantum computers are developing more quickly than expected – and so is the threat to our current computer security ...

Quantum vendors and national agencies are aligning to establish common standards for logical qubits, which should enable ...

Google's quantum paper made headlines with that number. Here's what it means, what's actually at risk, and why 6.9 million ...

Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are practically impossible to solve. Quantum computers threaten to flip that ...

Quantum processors operate in environments engineered to eliminate nearly all external interference. That just might make them perfect dark matter detectors.

Other scientists have investigated the idea of a hidden structure further. David Bohm, a 20th-century physicist, built a ...

Charles H. Bennett and Gilles Brassard have spent more than four decades proving that the strange behavior of quantum ...
