Just a few years ago, many researchers in quantum computing thought it would take several decades to develop machines that ...

John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the technology that could deliver machines with unrivalled capabilities ...

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 ...

Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

Technique lays the groundwork for neutral-atom quantum computers with more than 100 000 qubits, say physicists ...

A new way of capturing light from atoms could finally unlock ultra-powerful, million-qubit quantum computers. After decades of effort, researchers may finally be closing in on a practical path toward ...

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 ...

It could take a supercomputer 149 million years to decrypt data that has been encrypted with the RSA-2048 public-key ...
