Physicists have designed the building blocks of quantum computer that works using sound

Arxiv – On-chip quantum phonodynamics (6 pages) ABSTRACT – Sound can be just as quantum as light. But our toolbox for single quanta of sound, i.e. phonons, is currently insufficient. Here we describe a new component that enables a chip-based, solid-state analogue of cavity-QED utilizing acoustic phonons instead of photons, phonitons instead of polaritons. We …

Background Radiation Levels

The U.K. Health Protection Agency estimates the typical Briton receives about 2,200 microsieverts of radiation per year from background radiation, or about 0.251 microsieverts per hour — more than double the levels registered in Tokyo. Rome is also about 0.25 microsieverts per hour. “Half of the average annual radiation to people in the U.K. comes …
