It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true.

As quantum computing develops, scientists are working to identify tasks for which quantum computers have a clear advantage over classical computers. So far, researchers have only pinpointed a handful ...

Explore the complex challenges of quantum gravity in this video, examining the evolution of gravity models and the necessity ...

Certain quantum phases, such as topological order, are notoriously difficult for computers to identify. The challenge grows with the correlation length, a measure of how far the p ...

A ‘quantum processor’ has solved a physics problem on the behaviour of magnetism in certain solids that would take the largest conventional supercomputers hundreds of thousands of years to calculate.

Researchers at Google have created an algorithm that can translate complex physical problems into the language of quantum mechanics, which could make quantum computers able to tackle more tasks. IBM’s ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem and opening paths to quantum teleportation and advanced quantum ...

STOCKHOLM, Sweden ‒ U.S.-based scientists John Clarke, Michel Devoret and John Martinis shared the 2025 Nobel Prize in Physics for "experiments that revealed quantum physics in action," paving the way ...

(HO/GOOGLE/AFP) The Nobel Prize in Physics was awarded to three scientists on Tuesday for discovering that a bizarre barrier-defying phenomenon in the quantum realm could be observed on an electrical ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...
