Two separate experiments have demonstrated the fast transport of trapped ions using trapping potentials that trace out the path for the ions to follow.

Quantum repeaters, devices that have been proposed for transporting encrypted information, could help collect light from distant telescopes in large area arrays.

Researchers measure the complex “shape” of individual photons, which could lead to new ways of encoding information.

With the right algorithm, quantum computers could tackle ubiquitous problems such as least-squares fitting of large data sets.
