A team of physicists from the University at Buffalo has developed a user-friendly method that allows researchers to solve complex quantum problems, once thought to require massive supercomputers, on ...

Quantum computers, systems that process information leveraging quantum mechanical effects, are expected to outperform classical computers on some complex tasks. Over the past few decades, many ...

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks. For ...

Quantum computers could soon be able to solve genuinely useful mathematical problems faster than classical computers, claims quantum computing firm Quantinuum. It would be the first example of these ...

At the forefront of discovery, where cutting-edge scientific questions are tackled, we often don’t have much data. Conversely, successful machine learning (ML) tends to rely on large, high quality ...

The original version of this story appeared in Quanta Magazine. For computer scientists, solving problems is a bit like mountaineering. First they must choose a problem to solve—akin to identifying a ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The recently rediscovered idea of quantum jamming complicates things. For the ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...
