Method for controlling quantum dot device by perturbing dangling bond electronic states

摘要

A quantum device is provided that includes controllably quantum mechanically coupled dangling bonds extending from a surface of a semiconductor material. Each of the controllably quantum mechanically coupled dangling bonds has a separation of at least one atom of the semiconductor material. At least one electrode is provided for selectively modifying an electronic state of the controllably quantum mechanically coupled dangling bonds. By providing at least one additional electron within the controllably quantum mechanically coupled dangling bonds with the proviso that there exists at least one unoccupied dangling bond for each one additional electron present, the inventive device is operable at least to 293 degrees Kelvin and is largely immune to stray electrostatic perturbations. Room temperature operable quantum cellular automata and qubits are constructed thereform.

1. A method for controlling a quantum device comprising:
placing an electrostatic species in proximity to a plurality of controllably quantum mechanically coupled dangling bonds so as to perturb an electronic state of said plurality of controllably quantum mechanically coupled dangling bonds of a material with each of said plurality of controllably quantum mechanically coupled dangling bonds having a separation from the remainder of said plurality of controllably quantum mechanically coupled dangling bonds of at least one atom of said material.
