A device that stores a single positron and controls its quantum states could measure its magnetic moment with unprecedented precision, testing a symmetry principle central to quantum field theory.

Topological superconductors hold promise for fault-tolerant quantum computing, but isolating signatures of the desired topological states has proven an elusive goal. A new study of an iron-based ...

Lab experiments provide new details about the charge-transfer process that occurs in ash clouds and other collections of particles. Electric volcano. Triboelectric charging caused by collisions of ash ...

According to the Heisenberg uncertainty principle, both the position and momentum of a quantum particle cannot be known with unlimited precision. In 1965, theorists showed that this principle does not ...
