Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

Stephen Hawking's theory of black hole evaporation clashes with the laws of quantum mechanics. A new paper finds a way around ...

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in ...

For the first time, physicists have entangled two atoms while they were in motion and used the result to run one of quantum ...

A cloud of helium atoms split, scattered and fell under gravity, yet still behaved as if its parts were linked. That is the ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades in the making, could help physicists probe the relationship between quantum ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

The Princeton Quantum Initiative’s Ph.D. program is helping pioneer a field that promises to define the next era of discovery ...

For the first time, scientists have directly imaged the quantum process underlying superconductivity, a phenomenon in which ...

Quantum key distribution (QKD) has been positioned as a physics-based method of securing encryption keys that cannot be ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...
