abstract

We consider methods for obtaining local lower bounds on characteristics of quantum (correspondingly, classical) systems, i.e. lower bounds valid in the trace norm $\epsilon$-neighborhood of a given state (correspondingly, probability distribution). The main attention is paid to infinite-dimensional systems.

Discussion (0). Continue with ORCID to comment.

  1. The Alicki-Fannes-Winter technique in the quasi-classical settings: advanced version and its applications

    quant-ph 2025-05 accept novelty 6.0 of 10

    An optimized version of the Alicki-Fannes-Winter technique yields strictly tighter semicontinuity and continuity bounds for several quantum and classical information characteristics.
