Death is the inescapable conclusion of life. But what happens after death is still a highly debated topic. Throw into the mix a heady combination of religious belief and scientific theories, and you ...

Scientists build a new light source for quantum communications by combining existing technologies together to create a stronger and more robust quantum signal. When you purchase through links on our ...

Google unveiled an experimental machine capable of tasks that a traditional supercomputer could not master in 10 septillion years. (That’s older than the universe.) Google’s quantum computing cooling ...

Could we live in a quantum multiverse without ever noticing its oddness? A simulation suggests that the answer may be “yes” surprisingly often. “We live in a quantum world, as far as the experiments ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

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 ...
