Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But ...

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

Researchers from the University of Waterloo's Faculty of Science and the Institute for Quantum Computing (IQC) are prioritizing collaboration over competition to advance quantum computer development ...

A Canadian quantum computing start-up claims its new qubit will enable much smaller and cheaper error-free quantum computers. But getting there will be a steep challenge. To correct its own errors, a ...

In today's edition of The Edward Snowden Files, The Washington Post reports that the National Security Agency, with a plan that sounds like something Lex Luthor cooked up, is racing to build a quantum ...

While quantum computers are already being used for research in chemistry, material science, and data security, most are still too small to be useful for large-scale applications. A study led by ...

PsiQuantum Inc., a well-funded quantum computing startup, said today it has raised $1 billion in late-stage funding to accelerate its efforts to build a large-scale, reliable quantum computer with ...

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

What do children's building blocks and quantum computing have in common? The answer is modularity. It is difficult for scientists to build quantum computers monolithically - that is, as a single large ...
