The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

A team of scientists has used a quantum processor to create an exotic new state of matter, capturing the strange motion of quantum particles in real time.

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number ...

Explore Google's breakthrough in quantum advantage, showcasing its Willow processor's ability to outperform supercomputers in ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

Qubits differ from classical bits, which are coded as only 0 or 1. A qubit can be a combination of both 0 and 1 simultaneously. One way to think of it is as a coin spinning between a 0 and a 1 axis.

Philip Ball dives into the challenges in developing quantum computing, and building up investments and users for the tech ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

Google Quantum AI’s new research revisits a 1960s idea for unforgeable “quantum money,” exploring how physics, not code, ...
