## Resource

Can time run backward? Using a quantum processor, scientists reversed a system’s evolution—restoring a dispersed quantum state to its original form. The result shows that, under controlled conditions, quantum algorithms can locally undo processes that normally increase disorder. It doesn’t break physics, but it reframes how we understand time, entropy, and control over quantum information. This episode includes AI-generated content.
