An international team of scientists led by the US Department of Energy’s Argonne National Laboratory explored the concept of reversing time in a first-of-its-kind experiment, managing to return a computer briefly to the past. The results, published March 13 in the journal Scientific Reports, suggest new paths for exploring the backward flow of time in quantum systems and present new possibilities for quantum computer program testing and error correction.
