Consequences of relativistic causality for measurements of nonlocal characteristics of composite quantum systems are investigated. It is proved that verification measurements of entangled states necessarily erase local information. A complete analysis of measurability of nondegenerate spin operators of a system of two spin-1/2 particles is presented. It is shown that measurability of certain projection operators which play an important role in axiomatic quantum theory contradicts the causality principle.

  1. Uncountably many inequivalent maximally entangled measurements for two qutrits

    quant-ph 2026-07 conditional novelty 7.0 of 10

    There are uncountably many locally inequivalent maximally entangled measurement bases for two qutrits, constructed from qutrit SICs, including the first wild error bases in dimension 3.
