Alphabet Inc. (NASDAQ:GOOGL) has demonstrated a new method for significantly cutting error rates in quantum computing operations on its Willow processor. The process, known as magic-state cultivation, checks candidate quantum states for mistakes and discards failed attempts. In testing, the technique produced prepared quantum states with a 99.99% logical fidelity, reducing error rates approximately 40-fold compared with uncultivated states.

Unreliable hardware and high error rates remain major hurdles to performing complex quantum calculations. By successfully filtering out errors and transferring cultivated states between different error-correction systems—color codes and surface codes—researchers showed that the technique can protect quantum information across multiple hardware approaches. The peer-reviewed findings were published in the journal Science on Oct. 15.

While the results mark an important technical milestone, they do not mean a commercially viable quantum computer is available yet. Alphabet researchers noted that the technique must still be proven on a larger scale, and significant engineering obstacles remain before building fault-tolerant quantum machines for commercial use. In recent trading, Alphabet Class A shares traded down 2.47% at 340.6 USD, while Class C shares (NASDAQ:GOOG) fell 2.32% to 336.9 USD.
