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

We propose schemes to entangle two quantum dots (QDs) with the aid of Majorana fermions via optimal control. Two paradigmatic cases, the teleportation and the intradot spin flip processes, are considered, respectively, in the charge and spin degrees of QDs. We demonstrate that optimal control techniques can be effectively used to prepare entanglement between two QDs through manipulating their chemical potentials. Significantly, our optimal control generation of entangled states has a prominent advantage: The runtime is much shorter than in adiabatic passage, providing a shortcut to adiabatic entanglement preparation.
