And can such a direction be reversed?<\/p>\n<p>A new study, published in <a href=\"https:\/\/www.nature.com\/articles\/s41598-019-40765-6\">Scientific Reports<\/a>, is providing an important point of discussion on the subject. An international team of researchers has constructed a time-reversal program on a quantum computer, in an experiment that has huge implications for our understanding of quantum computing. Their approach also revealed something rather important: the time-reversal operation is so complex that it is extremely improbable, maybe impossible, for it to happen spontaneously in nature.<\/p>\n<p>As far as laws of physics go, in many cases, there\u2019s nothing to stop us going forward and backward in time. In certain quantum systems it is possible to create a time-reversal operation. Here, the team crafted a thought experiment based on a realistic scenario.<\/p>\n<p><!-- Link: <a href=\"https:\/\/www.iflscience.com\/physics\/scientists-have-reversed-time-inside-a-quantum-computer-and-the-implications-are-huge\/\">https:\/\/www.iflscience.com\/physics\/scientists-have-reversed-...-are-huge\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Time: it\u2019s constantly running out and we never have enough of it.
