Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article delves into the distillability problem of two-copy Werner states, specifically examining matrices A and B with at most four nonzero entries. It tackles Conjecture 1, a long-standing challenge in entanglement theory, by presenting new theorems and lemmas that characterize matrices with limited nonzero entries. The research is significant for quantum information tasks that require pure entangled states, as it contributes to the understanding of entanglement distillation and related quantum phenomena. The paper reviews the origin of Conjecture 1 and its relevance to various quantum information problems, making it a valuable resource for professionals in the field.
