Previous estimates demanded millions of qubits for quantum decryption. New research shows that just 10,000 movable atoms, like abacus beads, will do. With laser tweezers and error-correcting codes, RSA-2048 could be broken in days.

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
