A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the ...

Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already ...

Physicists have used atoms to reveal bizarre evidence that photons can experience negative time inside atomic clouds.

It’s been 37 years since scientists first demonstrated the ability to move single atoms, suggesting the possibility of designing materials atom by atom to customize their properties. Today ...

Qubits can also experience entanglement—a special quantum connection that enables operations on one qubit to affect another ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

From nearly indestructible metals, like tungsten, to delicate clouds in the sky, atoms make up everything around us. But do these atoms ever touch each other? As with most topics in atomic physics, ...

Researchers have uncovered a new principle that could accelerate the development of cheaper and more efficient fuel cells by ...

Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold gas of atoms confined to a single line, countless collisions occur—but ...

Traditionally, scientists have measured gravity’s influence on atoms by tracking how fast atoms tumble down tall chutes. Such experiments can help test Einstein’s theory of gravity and precisely ...
