The innovations in quantum computing are promising to herald a new era of mind bending advances in areas like climate change, drug design, and finance, but what actually is a quantum computer, how are ...

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university ...

To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

Big Four firm Ernst and Young announced it now has a quantum computer physically sitting in its Toronto office.

Netherlands-based QuiX Quantum has delivered Carina, the world's first universal photonic quantum computer designed for customer deployment. Unlike most quantum machines, Carina operates at room ...

Bitcoin’s security relies on elliptic curve cryptography, a one-way mathematical function that makes deriving a private key from a public key effectively impossible for traditional computers. Shor’s ...

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 ...

Governments and technology companies are fueling an urgent, high-stakes race to develop quantum power, which promises to revolutionize- and potentially compromise - global security Quantum computing ...

Quantum advantage? Sure sounds like AT&T is getting it from a D-Wave partnership. Maybe not exactly quantum supremacy just ...
