Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Scientists may have finally unlocked the unusual role quasiparticles known as "anyons" play in a pair of quantum experiments ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

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 ...

With the help of a new experiment, researchers have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects of quantum mechanics -- the ...

Jim Baggott is a science writer based in Cape Town, South Africa. He is co-author with John Heilbron of Quantum Drama. Quantum mechanics is an extraordinarily successful scientific theory, on which ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, connects quantum mechanics to infinitely intricate mathematical structures. Hofstadter was ...
