The fundamental resource that drives a quantum computer is entanglement—the connection between two distant particles which Einstein famously called 'spooky action at a distance'.

Physicists at the National Institute of Standards and Technology (NIST) have found a way to manipulate atoms' internal states with lasers that dramatically influences their interactions in specific ways.

A discovery by physicists at UC Santa Barbara may earn silicon carbide –– a semiconductor commonly used by the electronics industry –– a role at the center of a new generation of information technologies designed to exploit quantum physics for tasks such as ultrafast computing and nanoscale sensing.

Thanks to advances in experimental design, physicists at the National Institute of Standards and Technology (NIST) have achieved a record-low probability of error in quantum information processing with a single quantum bit (qubit)—the first published error rate small enough to meet theoretical requirements for building viable quantum computers.

Physicists have discovered that the quantum properties of ions can be manipulated using microwaves, instead of lasers.

Dr Xiao-Qi Zhou and colleagues at the University of Bristol's Centre for Quantum Photonics and the University of Queensland, Australia, have shown that controlled operations — ones that are implemented on the condition that a "control bit" is in the state 1 — can be dramatically simplified compared to the standard approach.


Word of the Day
postliminy
  • In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
  • In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
The word 'postliminy' comes from a Latin word meaning 'threshold'.
