We show that the incompatibility of a set of measurements cannot be increased by subjecting them to a filter, namely, by combining them with a device that post-selects the incoming states on a fixed outcome of a stochastic transformation. This result holds for several measures of incompatibility, such as those based on robustness and convex weight. Expanding these ideas to Einstein-Podolsky-Rosen steering experiments, we are able to solve the problem of the maximum steerability obtained with respect to the most general local filters in a way that allows for an explicit calculation of the filter operation. Moreover, our results generalize to nonphysical maps, i.e., positive but not completely positive linear maps.

  1. Operational Coherent Measurements with Steering and Randomness

    quant-ph 2025-11 reject novelty 6.0 of 10

    Coherent measurements are claimed to be exactly those that can demonstrate SDI steering, enabling randomness certification from separable isotropic states even at arbitrarily low detection efficiency.

  2. All incompatible sets of measurements can generate Buscemi nonlocality

    quant-ph 2025-08 unverdicted novelty 6.0 of 10

    Every incompatible measurement set, including Bell-local ones, can generate nonlocality in a quantum-input (Buscemi) scenario, and the extractable amount is capped by the degree of incompatibility.

  3. Dynamical Landauer principle: Thermodynamic criteria of transmitting classical information

    quant-ph 2025-02 conditional novelty 6.0 of 10

    One-shot classical capacities equal, up to error terms, the extractable work from correlations after transmission, yielding the equivalence n bits = n times kBT ln2 of transmitted energy.
