Measurement incompatibility cannot be stochastically distilled

HY Ku, CY Hsieh, C Budroni - arXiv preprint arXiv:2308.02252, 2023 - arxiv.org
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 …
