Published April 28 in Nature, the paper shows how to bring multiple molecules at once into a single quantum state -- one of the most important goals in quantum physics. > "People have been trying to do this for decades, so we're very excited," said senior author Cheng Chin, a professor of physics at UChicago who said he has wanted to achieve this goal since he was a graduate student in the 1990s. "I hope this can open new fields in many-body quantum chemistry. There's evidence that there are a lot of discoveries waiting out there."
