Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don't work reliably or even at all, such as indoors, in urban canyons, underwater and underground.
Scientists claim to have produced the first-ever blueprint for a large-scale quantum computer in a development that could bring about a technological revolution on a par with the invention of computing itself.
In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a particle of light. The particle of light, or photon, can then act as a messenger to carry the information to other electrons, creating connections that form the circuits of a quantum computer.
Researchers have observed quantum effects in electrons by squeezing them into one-dimensional 'quantum wires' and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.
Harnessing the weirdness of the quantum world is difficult — fragile quantum properties quickly degrade under typical conditions. But such fragility could help migrating birds find their way, scientists report in the June New Journal of Physics.
