Scientists have always wondered whether ordinary materials are also secretly held together by quantum connections. Until now, there seems to be no way to answer this question.
However, recently, a team of researchers has demonstrated a technique that can directly detect entanglement inside solids. So instead of guessing or relying purely on theory, scientists can now directly measure how entangled a material is—an essential step for designing better quantum devices.
Moreover, according to the researchers, their technique works even when there is no perfect theoretical model of the material, and the sample is not pure (which is often the case in real-world materials).
“We’ve found that it works 100 percent,” Allen Scheie, one of the researchers and a condensed matter physicist at Los Alamos National Laboratory in New Mexico, said.
