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 two groundbreaking schemes for generating four-photon cluster states, essential for robust quantum computing and communication. The schemes leverage quantum dot microcavity coupling systems, which offer advantages such as non-interacting photon nature and precise single qubit measurement. The first scheme employs four single-photon states and three quantum dot microcavity coupling systems, while the second scheme uses EPR states and a single-sided quantum dot microcavity system. Both schemes demonstrate high fidelity and efficiency under ideal conditions but are impacted by factors like coupling strength and side leakage rate in practical scenarios. The article thoroughly discusses these factors and compares the two schemes, providing valuable insights for practical implementation.
