In quantum computing, every step is reversible, like a dance. Irreversible processes, where a step cannot be undone, are like a dancer vanishing. If such processes were easily accessible, the computer would gain fantastic power. But that very power hints that nature imposes a hard barrier.

Researchers have proved that even a tiny quantum processor can outperform massive classical computers in sorting and analyzing big data. The 'quantum sketch' algorithm was successfully used to decode genes in individual cells and to gauge the sentiment of movie reviews. All of this was accomplished
