174 results about "Mixed states" patented technology

A mixed quantum state is a statistical ensemble of pure states (see quantum statistical mechanics). Mixed states inevitably arise from pure states when, for a composite quantum system H 1 ⊗ H 2 {\displaystyle H_{1}\otimes H_{2}} with an entangled state on it, the part H 2 {\displaystyle H_{2}} is inaccessible to the observer.

Cleaning equipment and use thereof

By constructing tank cleaning equipment according to the invention such that it comprises a cleaning jetting part (7, 9) as well as a suction part (4), the equipment can work with the same cleaning medium which is recirculated. This saves supply of fresh cleaning medium, and since used medium is thus not discharged, it is not necessary to establish deposit facilities to avoid pollution. Furthermore, this equipment according to the invention may advantageously be used for keeping so-called drilling mud in a mixed and thus ready-to-use state, even when left to stand for an extended period of time in a tank. The nozzle jets (10) thus keep the mud in the tank in a constantly mixed state, and the mud can therefore be sucked through the suction pipe (20) for pumping in the drill pipe, it being ensured that the mud is homogeneous and has a suitable viscosity.

Method for detection and imaging over a broad spectral range

A method of controlling the coordinate sensitivity in a superconducting microbolometer employs localized light, heating or magnetic field effects to form normal or mixed state regions on a superconducting film and to control the spatial location. Electron beam lithography and wet chemical etching were applied as pattern transfer processes in epitaxial Y—Ba—Cu—O films. Two different sensor designs were tested: (i) a 3 millimeter long and 40 micrometer wide stripe and (ii) a 1.25 millimeters long, and 50 micron wide meandering-like structure. Scanning the laser beam along the stripe leads to physical displacement of the sensitive area, and, therefore, may be used as a basis for imaging over a broad spectral range. Forming the superconducting film as a meandering structure provides the equivalent of a two-dimensional detector array. Advantages of this approach are simplicity of detector fabrication, and simplicity of the read-out process requiring only two electrical terminals.
