The wave inside the container is magnified. Outside, the energy waves wrap as if they had never encountered any obstacle. (Gunther Uhlmann/University of Washington) A new system has been theorized by an international team of mathematicians that could conceal matter in the form of energy […]

To actually build efficient quantum computers remains a significant challenge in practice. A new scheme termed “coherent photon conversion”, could potentially overcome all of the currently unresolved problems for optical implementations of quantum […]

Their latest work describes how the size of light-absorbing particles–quantum dots–affects the particles’ ability to transfer energy to electrons to generate electricity. The results are published in the April issue of the journal ACS […]
