Rare quantum state reveals particles with quarter-electron charge
An electron's charge is normally fixed, like a coin you can't break into pieces. But if electrons are cooled close to absolute zero and trapped in a two-dimensional layer under a powerful magnetic field, they organize into ...

Random access quantum memory lets one processor select among seven storage cells
Classical computers can temporarily store the information required to perform specific tasks in a short-term memory component known as RAM (random access memory). This component allows computer processors to retrieve information ...
Cosmic lockdown: How the environment can isolate quantum fields
A simplified cosmological model suggests that decoherence can suppress quantum tunneling, effectively locking fields into the vacuum state they have reached.

Higher-dimensional black holes hide an exact symmetry in their ringing, and string-inspired gravity breaks it
Strike a bell, and it rings with a pitch and a fading that tell you about the bell: its size, its shape, the metal it is made of. Black holes ring too. When two merge, the newborn black hole shivers and sheds gravitational ...
Vertical quantum sensor could reveal nanoscale magnetic patterns in quantum materials
Quantum materials do things ordinary materials cannot. They carry current without any loss, or conduct only along their outer edge while the inside insulates. Future quantum computers and quantum sensors will run on materials ...
