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 an alternative scheme for programmable quantum gates specifically designed for polarization qubits of single photons. Unlike the conventional approach based on the scheme of Reck et al., we adopt the Hilbert-space expansion technique to enable a novel feature in the design of arbitrary quantum operations. We present a scheme that independently programs each matrix element of an operator. The proposed scheme can support the realization of many kinds of quantum operations. In anticipation of advances in the current quantum photonics technology, we assume the manipulation and detection of many photon qubits and propose a theoretical scheme to achieve n-polarization-qubit optical reconfigurable quantum gates by linear optical elements.
