  • Patent number: 11556829
    Abstract: Aspects of the present disclosure describe techniques for controlling quantum states of ions in an ion chain for a quantum operation. For example, a method is described that includes providing, from a first direction, a global optical beam to the ions in the ion chain, and providing, from a second direction different from the first direction, to each ion in a subset of the ions in the ion chain, a respective addressing optical beam. The method further includes dynamically controlling each of the addressing optical beams being provided by using a respective channel in a multi-channel acousto-optic modulator (AOM) to implement, with the ion chain, one or more quantum gates in a sequence of quantum gates of the quantum operation. Aspects of a quantum information processing (QIP) system that includes the multi-channel AOM for performing the method are also described.

  • Patent number: 7380799
    Abstract: An adjustable vehicle suspension system includes a plurality of damping members and an air spring operatively associated with each of the damping members. The suspension system also includes a compressed air source, a valve assembly, and a controller. The compressed air source is in fluid communication with each of the air springs. The valve assembly is operatively disposed between the compressed air source and each of the air springs. The controller is operatively associated with the valve assembly for selective activation thereof. A user can selectively adjust one of a damping rate of the damping members, a spring rate of the air springs, and a ride height of the air springs, such as by using a control panel. A method is also disclosed.
