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 introduces a Quantum Digital Signature (QDS) scheme based on superdense teleportation, addressing the security challenges posed by quantum algorithms to classical digital signatures. This scheme, built on the principles of quantum mechanics, offers unconditional security and can be used to sign multi-bit messages efficiently. The authors describe the three-stage process of the QDS scheme, including the initial stage where quantum channels are set up, the signing stage where the signature state is transmitted via quantum teleportation, and the verifying stage where the message is validated. The scheme's advantages include not requiring an arbitrator and providing a straightforward method for signing multi-bit messages. The authors also discuss the security aspects of the scheme, including correctness, unforgery, and non-repudiation, and compare it with previous QDS schemes.
