In a step that brings silicon-based quantum computers closer to reality, researchers have built a device in which a single electron can pass its quantum information to a particle of light.
Little is rarer than an observable quantum spin liquid, but now, tests reveal that a synthetic crystal with ytterbium as its base may house one at near absolute zero.
How can quantum information be stored as long as possible? An important step forward in the development of quantum memories has been achieved by a research team of TU Wien.
"Our result says that, in principle, we can engineer 'rain gutters' and 'gates' in a system to manipulate quantum objects, either after they land or during their actual flow."
