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

Quantum digital signature (QDS) in principle can provide the information-theoretic security based on the laws of quantum mechanics. The scheme of quantum digital signature that does not require trusted quantum channels has been presented. However, the performance in both signature rate and transmission distance remains to be improved. In this paper, we present a scheme on implementing the single-photon-added coherent state (SPACS) into QDS. We use the BB84 protocol as an example and compare its performance with the case of using the weak coherent state (WCS). Our simulation results indicate that the performance of the QDS system utilizing SPACS can greatly exceed those using WCS.
