University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

Quantum physics and Einstein's theory of general relativity are the two pillars upon which our understanding of the Universe is based, each excelling in describing phenomena at its own scale. However, ...

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

Almost every technological process depends in some way on temperature measurement and control — think intercontinental flights, fresh bread, or reliable electricity. They all depend on a sophisticated ...
