Qntm

Sam Hughes (born 1983), known online as and publishing under the pen name qntm (pronounced "quantum"), is a British programmer and science fiction author. Hughes writes short stories such as Lena, about the first digital snapshot of a human brain, and serial novels such as Ra and Fine Structure. He has also written for the SCP Foundation wiki. His book There Is No Antimemetics Division, a high-concept blend of science fiction and cosmic horror, began as a series on the wiki. In 2024, Del Rey Books acquired UK and Commonwealth rights to the book, while Ballantine Books acquired the US rights. qntm also contributed to SCP-055 alongside user CptBellman.

In 2022, Hughes created Absurdle, a variant of Wordle wherein the word changes with every guess, while still remaining true to previous hints. The Guardian described it as "the Machiavellian version of Wordle", and Hughes described it as an "experiment to find the most difficult [...] variant of Wordle", comparing it to one of his previous projects, the Tetris variant Hatetris.
