  • Patent number: 11454834
    Abstract: Novel and useful quantum structures having a continuous well with control gates that control a local depletion region to form quantum dots. Local depleted well tunneling is used to control quantum operations to implement quantum computing circuits.

Complex structures with a higher number of qdots per continuous well and a larger number of wells are fabricated. Both planar and 3D FinFET semiconductor processes are used to build well to gate and well to well tunneling quantum structures. Combining a number of elementary quantum structure, a quantum computing machine is realized. An interface device provides an interface between classic circuitry and quantum circuitry by permitting tunneling of a single quantum particle from the classic side to the quantum side of the device.

  • Patent number: 11366345
    Abstract: Novel and useful quantum structures that provide various control functions. Particles are brought into close proximity to interact with one another and exchange information. After entanglement, the particles are moved away from each other but they still carry the information contained initially. Measurement and detection are performed on the particles from the entangled ensemble to determine whether the particle is present or not in a given qdot. A quantum interaction gate is a circuit or structure operating on a relatively small number of qubits. Quantum interaction gates implement several quantum functions including a controlled NOT gate, quantum annealing gate, controlled SWAP gate, a controlled Pauli rotation gate, and ancillary gate. These quantum interaction gates can have numerous shapes including double V shape, H shape, X shape, L shape, I shape, etc.

  • Patent number: 11327345
    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.
