Abstract: A quantum circuit that is a quantum random access memory that can write basis states of a weighted superposition in real time into a memory cell or a superposition of memory cells. The quantum circuit is a quantum random access memory that can write a prepared superposition. The quantum circuit is a quantum random access memory that can write classical data.

Abstract: A quantum circuit, including, a first S gates, a first Toffoli gate, a Controlled-SWAP gates, a Controlled-Toffli gates, a second Toffoli gate, and a second S gates.

Abstract: A method of decontaminating naturally occurring radioactive material (NORM) from downhole equipment may include injecting a NORM dissolver into an isolated region of a wellbore in which NORM-contaminated production equipment is located; and removing the NORM contaminants from the production equipment. The method may also include recommencing production of hydrocarbons following the decontamination.

Abstract: The present invention is directed to an camera, an imaging system and an illumination sensor which all corrects colors of taken images of objects at practical speed and displays the image colors correctly. The invention comprises an imaging device for taking a color image and a lens, and a reflection surface is provided within the maximum field of view to diffuse-reflect an image of an object so that it impinges upon the imaging device through the lens. Each main coordinates of a direct image obtained as an object point on the object is imaged on the imaging device is assigned to corresponding sub-coordinates of an indirect image of the object point formed from the reflection surface on the imaging device. The R, G, B components in pixels at the individual main coordinates are respectively divided by the same components at the corresponding sub-coordinates to provide a color-corrected image.
