Coupled quantum dots may offer a new way to store quantum information
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have for the first time created and imaged a novel pair of quantum dots—tiny islands of confined electric charge that act like interacting artificial atoms. Such “coupled” quantum dots could serve as a robust quantum bit, or qubit, the fundamental unit of information for a quantum computer. Moreover,…
Adiabatic shortcuts: Short and sweet in the quantum world
Completing a task slowly and carefully may provide us with a high-quality product. It can be summed up by the popular adage “easy does it.” But what if a high price has to be paid for slowness? Time is a scarce resource and, what is more, a good result is not guaranteed, since we may be easily disturbed or interrupted by…
Quantum sensor breakthrough using naturally occurring vibrations in artificial atoms
A team of scientists, led by the University of Bristol, have discovered a new method that could be used to build quantum sensors with ultra-high precision. …
