To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.

Deep in outer space, invisible hands mold the universe. One is dark matter, an unseen substance thought to bind distant galaxies. The other is dark energy, a force believed to push stellar structures ...

Physicists at the world's largest atom smasher have observed two quarks in a state of quantum entanglement for the first time. The ATLAS experiment (A Toroidal LHC Apparatus) is the largest detector ...

Researchers have developed an experimental method for determining whether the functions performed by a quantum computer are the result of quantum mechanics — or just a clever twist on classical ...

A new Physical Review Letters study places constraints on the ER = EPR conjecture, showing that under the authors' ...

When we observe the world at our scale, everything seems to obey predictable laws, those of classical physics. But when diving into the universe of particles, the rules change. Quantum phenomena often ...

Suppose you’re a CIO or senior application planner, and you need to understand whether you should dig into quantum computing as a future option. Enterprises themselves are divided on the issue, ...

Quantum effects are physical phenomena that cannot be explained accurately with classical mechanics alone. They arise from the wave-like and probabilistic behavior of matter and light: energy levels ...

This schematic shows how trapped ions in a figure-eight, spin-transparent storage ring could work as a quantum computer. NEWPORT NEWS, VA – Deep in outer space, invisible hands mold the universe. One ...
