Illustration showing photon emission from a nanodiamond being directed by a bullseye antenna. The bullseye antenna is shown flat, and seven parallel orange arrows representing photons emerge from different parts of the bullseye, like candles on a birthday cake. At the centre of the bullseye is a diamond

Chip-integrated nanoantenna efficiently harvests light from diamond defects

An illustration showing how vibrations in one side of the splitter become coupled to the other side. The two waveguides are shown as long, narrow purple blocks that overlap for part of their length. In the area of overlap, a big blue-and-yellow wave envelope that enters the picture via one waveguide is split into two smaller-magnitude wave envelopes travelling through both waveguides.

Single-phonon coupler brings different quantum technologies together

Waveguide-style approach promises to pair the versatility of phononic quantum technologies with the tight control of photonic ones

Image showing a model city with various data transmission use cases highlighted. Base stations used to cover rural areas use sub-6G frequencies. Various base stations used in ultra-dense areas use microwave wavelengths. Satellite and vehicle-to-everything communications use millimetre wavelength. Holographic and remote surgery uses sub-THz to THz wavelengths. A set of circuits and signals at the bottom of the diagram shows how signals become noisier with conversion from one band to another.
