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 evolution of quantum key agreement (QKA) protocols, highlighting the shift from two-party to multi-party systems. It critically examines existing protocols, noting vulnerabilities and inefficiencies, particularly in participant authentication and quantum resource management. The proposed protocol addresses these issues by employing d-level single-particle states and quadratic hash functions, ensuring robust security and fairness. The protocol's circular structure for particle transport and efficient use of quantum resources are key innovations, setting it apart from traditional methods. The article provides a detailed theoretical foundation, a step-by-step protocol description, and a comprehensive security and efficiency analysis, making it a significant contribution to the field of quantum cryptography.
