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

This article delves into the realm of counterfactual quantum networks, focusing on the utilization of multipartite GHZ entangled states to revolutionize quantum communication. The text explores the application of counterfactual CNOT gates and all-photonic quantum repeaters to achieve efficient entanglement swapping and distribution. A significant aspect of the research is the development of a quantum network model that enhances communication efficiency without the need for physical particle transmission. The article also discusses the success probability and fidelity of the proposed protocol, highlighting its advantages over existing methods. The findings suggest that this protocol can serve as a critical building block for future quantum networks, facilitating communication between multiple users and information units. The research concludes with a comparison of the proposed protocol's success efficiency with existing approaches, demonstrating its potential for long-distance quantum communication.
