Scientists ‘reverse time’ with quantum computer in breakthrough study

&gt; <i>The breakthrough study seems to contradict basic laws of physics and could alter our understanding of the processes governing the universe.</i><p>No. This is an expected theoretical result, but it&#x27;s very difficult to do it experimentally.<p>The other article in the front page has a less exaggerated coverage: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=19377827" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=19377827</a><p>[Feature request: Add a filter to automatically remove &quot;breakthrough&quot; from the titles.]

Is it reversing time if there is no time to reverse? It is moving the state of the system from disordered to ordered in a calculated way.
