Abstract: Methods and apparatus of quantum information processing using quantum dots are provided. Electrons from a 2DEG are confined to the quantum dots and subjected to a magnetic field having a component directed parallel to the interface. Due to interfacial asymmetries, there is created an effective magnetic field that perturbs the energies of the spin states via an interfacial spin-orbit (SO) interaction. This SO interaction is utilized to controllably produce rotations of the electronic spin state, such as X-rotations of the electronic spin state in a double quantum dot (DQD) singlet-triplet (ST) qubit. The desired state rotations are controlled solely by the use of electrical pulses.

A cowl louver that makes up a portion of the vehicular cowl louver assembly has one or more recesses formed in an upper-facing surface with which to provide storage of an ice scraper. A resiliently-biased clip allows the ice scraper to be selectively removable from the cowl louver to enable a person to scrape ice, snow or other debris from a vehicular windshield.
