A classical algorithm solves the boson sampling problem for 30 bosons with standard computing hardware, suggesting that a much larger experimental effort will be needed to reach a regime where ...

A tool that can watermark text generated by large language models, improving the ability for it to identify and trace synthetic content, is described in Nature this week.

We establish an upper bound for the entropy, based on the eigenvalue interlacing property, and we incorporate this bound in a branch-and-bound algorithm for the exact solution of the problem. We ...

A new software devised by scientists could enable a common laboratory device to virtually separate a whole-blood sample into its different cell types and detect important gene-activity changes ...
