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 performance of remote state preparation under fluctuating electromagnetic fields, focusing on the impact of vacuum fluctuations, acceleration, atomic polarization, and boundaries on the fidelity of state preparation. It introduces a scheme for remote state preparation affected by fluctuating electromagnetic fields, involving two users, Alice and Bob, and discusses the evolution process of the communication system. The authors derive the necessary coupled differential equations and solve them to obtain the fidelity as a function of time and various parameters. The results reveal that vacuum fluctuations and acceleration cause fidelity attenuation, while the presence of a boundary can protect the fidelity depending on the atomic position and polarization. This research offers valuable insights into improving and adjusting the performance of remote state preparation in practical scenarios, highlighting the effects of field fluctuations, boundary effects, and the Unruh effect through quantum information means.
