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 challenges and potential solutions for practical implementations of continuous-variable quantum teleportation (CVQT) using the Braunstein-Kimble protocol. It discusses the limitations posed by finite squeezing and lossy channels, and introduces photon catalysis as a promising technique to improve fidelity and extend transmission distances. The paper presents both single-side and bilateral symmetrical photon catalysis schemes, demonstrating their effectiveness through numerical simulations. The findings highlight the potential of non-Gaussian operations to enhance entanglement and improve the overall performance of CVQT systems, making it a valuable read for professionals in the field of quantum communications.
