The quantum properties of light are well studied and have been extensively used to reveal some of the fundamental aspects of quantum mechanics. Efforts now are under way to leverage the “quantum advantage” offered by quantum entanglement for practical applications such as enhanced imaging, sensing, and communications. A viable quantum technology, however, will require a shift from the optical bench to a miniaturized on-chip platform. Holtfrerich et al. show that the quantum properties of optically entangled images are preserved as they are transmitted to distant plasmonic structures, where they convert to nanometer-scale electronic excitations before being converted back to light.
