The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

In an article published in Communications Physics, researchers from the Université libre de Bruxelles and the Institute for ...

One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 quantum bits ...

Assigning ends of the system the standard experimental nicknames of Alice and Bob, the task required Alice to create a ...

Researchers kept more than 6,000 qubits coherent while operating with 99.98% accuracy. Here's why that matters for quantum ...

Scientists have linked nuclear spins inside silicon chips, marking a leap toward scalable quantum computers. Engineers at UNSW have achieved a major breakthrough in quantum computing by creating what ...

A hidden quantum geometry that distorts electron paths has finally been observed in real materials. This “quantum metric,” once thought purely theoretical, may revolutionize electronics, ...

This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the ...

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 ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

Imagine you are out on a walk. Outside the house in the fresh air you may have left the walls behind, but even so there are boundaries that limit where you can wander. In a city, you are constrained ...

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a ...
