Abstract: Quantum dot devices with three of more accumulation gates provided over a single row of a quantum dot formation region are disclosed. Each accumulation gate is electrically coupled to a respective doped region. In this manner, multiple single electron transistors (SETs) are provided along the row. Side and/or center screening gates may be used to apply microwave pulses for qubit control and to control electrostatics so that source and drain regions of the multiple SETs with quantum dots formed along the single row of a quantum dot formation region are sufficiently isolated from one another. Such quantum dot devices provide strong spatial localization of the quantum dots, good control over quantum dot interactions and manipulation, good scalability in the number of quantum dots included in the device, and/or design flexibility in making electrical connections to the quantum dot devices to integrate the quantum dot devices in larger computing devices.

Abstract: Adjustable angle floor support for plumb and level free standing erection of portable room divider wall and screen panels, including a lower load bearing leg section for mounting on a floor engaging foot and which has a laterally directed load bearing engagement face, an upper load transmitting leg section for receiving in load bearing relation thereon the portable room divider panel and which has a cooperating laterally directed load transmitting engagement face, and releasable positioning means, such as a transverse locking tension screw, adjustably operatively interpositioning about an axis of pivot the upper leg section on the lower leg section with the engagement faces in opposed direct load bearing releasable interengaging contact for relative angular displacement, preferably of limited range, between the leg sections about the axis of pivot for plumb and level adjustment.
