Scientists have succeeded in taking repeated measurements of the spin of an electron in a silicon quantum dot (QD), without changing the spin in the process. This type of 'non-demolition' measurement ...

Quantum control and dynamics is an emerging interdisciplinary field that seeks to manipulate quantum systems through tailored control strategies. By integrating advanced feedback mechanisms, ...

Systems in which mechanical motion is controlled at the level of individual quanta are emerging as a promising quantum-?technology platform. New experimental work now establishes how quantum ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

A reliable quantum internet is now one step closer to reality. A research team at Stony Brook University is successfully tackling the major challenges of building a quantum internet testbed by ...

Extra spooky: Artist's impression of entangled and delocalized atoms within the interferometer. (Courtesy: Steven Burrows, Thompson group/JILA) For most people, quantum mechanics seems pretty weird.

Quantum superposition is a fundamental and also intriguing property of the quantum world. Because of superposition, a quantum system can be in two different states simultaneously, like a cat that can ...

A group of scientists from the RIKEN Center for Emergent Matter Science in Japan have succeeded in taking repeated measurements of the spin of an electron in a silicon quantum dot (QD), without ...

When thinking about quantum mechanical systems, single photons and well-isolated ions and atoms may spring to mind, or electrons spreading through a crystal. More exotic in the context of quantum ...
