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 advanced technique of quantum ghost imaging, which involves the detection of photons that have interacted with an object without using a spatially resolving sensor. The authors explore the use of four-wave back-mixing to improve the diffraction limit, allowing for higher-quality images with enhanced spatial resolution. This method eliminates the strict phase-matching requirements of traditional setups, offering a significant advantage over existing techniques. The authors also discuss various optical setups and the impact of diffraction on image quality, providing a comprehensive analysis of the proposed method's benefits and potential applications.
