Using sound to remember quantum information 30 times longer

While conventional computers store information in the form of bits, fundamental pieces of logic that take a value of either 0 or 1, quantum computers are based on qubits. These can have a state that is simultaneously both ...

Q&A: How permanent is permafrost with increasing temperatures?

One of the defining features of an arctic environment is permafrost, which covers almost 10% of Earth's surface and remains entirely frozen year round. With temperatures reaching more extreme levels more frequently, the U.S. ...

Powerful form of quantum interference paves the way for phonon-based technologies

Just as overlapping ripples on a pond can amplify or cancel each other out, waves of many kinds—including light, sound and atomic vibrations—can interfere with one another. At the quantum level, this kind of interference ...

Wave-like domain walls drive polarization switching in sliding ferroelectrics, study finds

Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, they produce ferroelectric ...

Rogue waves demystified: Giant seas are just the ocean's 'bad day'

On New Year's Day 1995, a monstrous 80-foot wave in the North Sea slammed into the Draupner oil platform. The wall of water crumpled steel railings and flung heavy equipment across the deck—but its biggest impact was what ...
