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 intriguing phenomenon of star network quantum steering, a manifestation of quantum correlations in star network configurations. It introduces the star network local hidden state (SNLHS) model and examines how entanglement and steerability of independent resources contribute to star network steering. The paper also considers scenarios with one untrusted intermediate party and explores various combinations of resources, demonstrating how certain configurations can lead to global network steering. Notably, the authors prove the superactivation phenomenon in star network steering, showcasing how multiple copies of an entangled state can exhibit steering when a single copy cannot. This research offers valuable insights into the behavior of quantum correlations in complex network structures, contributing to the broader understanding of quantum information theory.
