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

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 ...

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

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

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 ...

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

Christopher Nolan's new film 'Oppenheimer' features complex science. He brought on scientists to make sure he got it right, but they said they didn't have to do much. Nolan had researched enough about ...

Scientists recently created a never-before-seen four-atom molecule — the coldest of its kind ever made. Researchers created the oddball molecule — a strange configuration of sodium-potassium with an ...
