Physicists couple key components of quantum technologies

0 Comments , , , , , , ,

Researchers are engaged in intensive work on the components of quantum technologies – these include circuits processing information using single photons instead of electricity, as well as light sources producing such quanta of light. Coupling these components to produce integrated quantum optical circuits on chips presents a challenge. Researchers have developed an interface that couples light sources for single photons with nanophotonic networks consisting of photonic crystals which can be replicated by using established nanofabrication processes.

Costs of natural disasters are increasing at the high end

0 Comments , , , , , , , ,

While the economic cost of natural disasters has not increased much on average, averages can be deceptive. The costs of major disasters like hurricanes Katrina, Maria and Dorian or the massive tornado swarms in the Midwest have increased to a disproportionately larger extent than those of lesser events, and these major disasters have become far more expensive, according to an international team of researchers.
