Abstract
We improve the lower bound on worst case trace reconstruction from to . As a consequence, we improve the lower bound on average case trace reconstruction from to .
Nous améliorons la borne inférieure, dans le cas pire, de la reconstruction par trace de à . Comme conséquence, nous améliorons la borne inférieure, dans le cas moyenné, de la reconstruction par trace de à .

I would like to thank Omer Tamuz for introducing me to the wonderful trace reconstruction problem, and for helpful discussions. I would also like to thank Russell Lyons for much helpful feedback on the paper, and for a bijective proof of Lemma 1. Finally, I would like to greatly thank an anonymous referee for several helpful comments, substantially improving the paper’s readability and understandability.
