Abstract
Novel and useful electronic and magnetic control of several quantum structures that provide various control functions. An electric field provides control and is created by a voltage applied to a control terminal. Alternatively, an inductor or resonator provides control. An electric field functions as the main control and an auxiliary magnetic field provides additional control on the control gate. The magnetic field is used to control different aspects of the quantum structure. The magnetic field impacts the spin of the electron by tending to align to the magnetic field. The Bloch sphere is a geometrical representation of the state of a two-level quantum system and defined by a vector in x, y, z spherical coordinates. The representation includes two angles θ and φ whereby an appropriate electrostatic gate control voltage signal is generated to control the angle θ of the quantum state and an appropriate control voltage to an interface device generates a corresponding electrostatic field in the quantum structure to control the angle φ.
