Made out of a fluorescent protein, the qubit is just 3 nanometers in diameter, scientists report August 20 in Nature. By hitting the protein with laser light, tweaking it with microwaves and observing ...

A new light-based method lets tiny quantum dots release perfectly controlled photons, opening doors to faster and cheaper ...

Quantum mechanics theory predicts that, in addition to exhibiting particle-like behavior, particles of all sizes can also ...

For more than a century, the laws of thermodynamics have helped us understand how energy moves, how engines work, and why time seems to flow in one direction. Now, researchers have made a similarly ...

Imagine if electricity could flow without resistance, or if computers could process data at unimaginable speeds. Achieving ...

Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful ...

CERN scientists have analyzed a particle of antimatter isolated in an undecided quantum state known as a superposition for the first time. While the quantum behavior of ordinary matter has been ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

A hidden world of quantum metrologists ensure that everyday devices perform safely and correctly, but their work is never done ...

In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.
