Researchers have now developed standards and calibrations for optical microscopes that allow quantum dots to be aligned with the center of a photonic component to within an error of 10 to 20 nanometers (about one-thousandth the thickness of a sheet of paper). Such alignment is critical for chip-scale devices that employ the radiation emitted by quantum dots to store and transmit quantum information ..read more

The 2023 Nobel Prize in Chemistry was focused on quantum dots -- objects so tiny, they're controlled by the strange rules of quantum physics. Quantum dots used in electronics are often toxic, but their nontoxic counterparts are being explored for uses in medicine and in the environment, including water decontamination. One team of researchers has specially designed carbon- and sulfur-based dots for these environmental applications ..read more

Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology. Addressing this need, a research team is now introducing a new approach for transducing quantum information: the team has manipulated quantum bits, so called qubits, by harnessing the magnetic field of magnons -- wave-like excitations in a magnetic material -- that occur within microsc ..read more
