Correction to: Nature https://doi.org/10.1038/s41586-020-03070-1 Published online 06 January 2021
In the ‘Projections to the future’ Methods section of this Article, owing to an error during the production process, the exponent in ‘2 trillion (1012)’ was incorrectly formatted as a reference citation (ref. 15), instead of being the correct exponent. The correct sentence is: “Thus, for a 9 × 4 matrix, four multiplexed input vectors and a modulation speed of 14 GHz, a processing speed of 2 trillion (1012) of MAC operations per second (9 × 4 MACs × 4 input vectors × 14 GHz) can be obtained.”. The original Article has been corrected online.
