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

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 ...

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 ...

Physicist Jay Gambetta, at IBM’s lab in Yorktown Heights, New York, explains how microwaves orchestrate a solution on a quantum chip: “Think of each qubit as a line in music. You’re creating notes.” ...

The day when quantum computers will be able to break conventional encryption is rapidly approaching, but not all companies ...

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