Rotating arrows instead of DNA letters allow comparing genomes hundreds of times faster and pave the way for quantum authentication.

DNA is a long carbon necklace made of four types of beads. Biologists often need to compare two strands to find differences. Normally this requires a lengthy brute-force search. Researchers came up with a clever trick: encode each bead as an arrow that rotates based on its neighbors. The idea came from language models, where words also 'know' context.

For similar DNA sequences, the arrows point in nearly the same direction. Similarity is measured by comparing arrow directions — which boils down to estimating the system's entropy.

The RotorMap method, using lightning-fast computation on GPUs, outperforms standard tools by 50–700 times. For quantum computers, a version was created where arrow directions determine particle states. The algorithm was tested on Quantinuum quantum machines, reading data via spectroscopy — analysis of emitted radiation.

The application is a quantum DNA signature, akin to an envelope that glows when opened. Any interception attempt is immediately noticeable, providing quantum protection for data.

The human genome is 3 billion letters. Comparing two genomes used to take hours, now it takes seconds.

Quantum DNA signatures resemble technology from 'Gattaca', but with protection that can't be hacked.
