Someday, somebody, somewhere will likely have a quantum computer capable of cracking the fragile codes that underpin every piece of data we exchange over the internet. We don’t know when. It could be ...

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 ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new experiment shows how to perform quantum operations while continuously fixing ...

Enabled by the introduction of its Willow quantum chip last year, Google today claims it's conducted breakthrough research that confirms it can create real-world applications for quantum computers.

Buterin warns that quantum computers could threaten Ethereum’s cryptography sooner than expected and outlines how the network can prepare safely. Buterin sees a nontrivial 20% chance that quantum ...
