Since Richard Feynman's first envisioned the quantum computer in 1982, there have been many studies of potential candidates -- computers that use quantum bits, or qubits, capable of holding an more than one value at a time and computing at speeds far beyond existing silicon-based machines for certain problems.

For most people, frustration is a condition to be avoided - but for scientists studying certain "frustrated" ensembles of interacting components – that is, those which cannot settle into a state that minimizes each interaction – it may be the key to understanding a host of puzzling phenomena that affect systems from neural networks and social structures to protein folding and magnetism.

Scientists at the National Institute of Standards and Technology (NIST) have developed the first "dimmer switch" for a superconducting circuit linking a quantum bit (qubit) and a quantum bus—promising technologies for storing and transporting information in future quantum computers.


Word of the Day
gawf
  • In costermongers' slang, a cheap red-skinned apple, which is rubbed hard with a cloth to give it the appearance and feeling of an apple of superior quality.
The origin of the word 'gawf' is obscure, but may come from the phrase 'go for more'.
