The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

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 ...

Believe it or not, the quantum vacuum... isn't completely empty. It has tiny vibrations or “sparks” of energy. If an object ...

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 ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

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

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 ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

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 ...
