(Phys.org) -- One of the main sticking points to creating a true quantum computer capable of performing meaningful work, is the problem of storing quantum state information in memory. Recent efforts have resulted in highly ...
(Phys.org) -- Quantum computers may someday revolutionize the information world. But in order for quantum computers at distant locations to communicate with one another, they have to be linked together in a network. While ...

(PhysOrg.com) -- For more than 40 years, scientists have been using the radiation pressure of light to move and manipulate small objects in space. But until now, the movements have always been restricted to very small scales, ...
Physicists at the National Institute of Standards and Technology have demonstrated an ion trap with a built-in optical fiber that collects light emitted by single ions (electrically charged atoms), allowing quantum information ...
