Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

Researchers from Google Quantum AI report that their quantum processor, Willow, ran an algorithm for a quantum computer that solved a complex physics problem thousands of times faster than the world's ...

The IBM Institute for Business Value (IBV) has published a beautiful book, good to read and also a substantial addition to any executive office: the fourth edition of The Quantum Decade. The 168-page ...

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

Conventional quantum algorithms are not feasible for solving combinatorial optimization problems (COPs) with constraints in the operation time of quantum computers. To address this issue, researchers ...

Peter Shor didn’t set out to break the internet. But an algorithm he developed in the mid-1990s threatened to do just that. In a landmark paper, Shor showed how a hypothetical computer that exploited ...

Quantum computers won’t break the internet tomorrow… but they will break your email security sooner than you think. Today, cybercriminals and state-sponsored groups are quietly collecting encrypted ...

The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has finalized a set of encryption algorithms designed to withstand cyberattacks from quantum computers. These ...
