'This moves the timeline forward significantly': Quantum computing breakthrough could slash pesky errors by up to 100 times

Quantum computing concept (artist's impression). A qubit, short for "quantum bit," is the fundamental unit of information in quantum computing. Unlike classical bits, which can be either 0 or 1, a qubit can exist in a superposition of both states simultaneously, enabling powerful computational possibilities - digitally generated image.

Researchers have discovered a way to speed up quantum error correction (QEC) by a factor of up to 100 — a leap that could significantly shorten the time it takes quantum computers to solve complex problems.

The technique, called algorithmic fault tolerance (AFT), restructures quantum algorithms so they can detect and correct errors on the fly, rather than pausing to run checks at fixed intervals.
