  • Patent number: 11423322
    Abstract: A novel and useful fully integrated quantum computer containing both quantum core circuitry and associated classical electronic control circuits on the same monolithic die. The integrated quantum computer avoids ESD loading on the quantum structures and minimizes the need for long interconnects with resultant large parasitic inductances and capacitances. Such parasitics reduce the maximum operating frequency of the realized quantum core structures. A cryostat unit functions to provide several temperatures to the quantum computer including a temperature to cool the quantum core to approximately 4° K and the interface SoC to 77° K. Alternatively, the interface circuitry is also integrated with the main QPU on the same die. A programmable pattern generator executes sequences of instructions that control the quantum core. In accordance with the sequences, a pulse generator functions to generate the control signals that are input to the quantum core to perform quantum operations.

  • 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.

  • Publication number: 20220149823
    Abstract: A novel and useful system and method of generating quantum unitary noise using silicon based quantum dot arrays. Unitary noise is derived from a probability of detecting a particle within a quantum dot array structure comprising position based charge qubits with two time independent basis states |0> and |1>. A two level electron tunneling device such as an interface device, qubit or other quantum structure is used to generate quantum noise. The electron tunneling device includes a reservoir of particles, a quantum dot, and a barrier that is used to control tunneling between the reservoir and the quantum dot. A detector circuit connected to the device outputs a digital stream corresponding to the probability of a particle of being detected. Controlling the bias applied to the barrier controls the probability of detection. Thus, the probability density function (PDF) of the output unitary noise can be controlled to correspond to a desired probability.

  • Patent number: 11327344
    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. Qubits are realized by modulating gate potential to control tunneling through local depleted region between two or more sections of the well. 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: 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.

  • Publication number: 20220137439
    Abstract: A novel and useful quantum computing machine architecture that includes a classic computing core as well as a quantum computing core. A programmable pattern generator executes sequences of instructions that control the quantum core. In accordance with the sequences, a pulse generator functions to generate the control signals that are input to the quantum core to perform quantum operations. A partial readout of the quantum state in the quantum core is generated that is subsequently re-injected back into the quantum core to extend decoherence time. Access gates control movement of quantum particles in the quantum core. Errors are corrected from the partial readout before being re-injected back into the quantum core. Internal and external calibration loops calculate error syndromes and calibrate the control pulses input to the quantum core.

  • Publication number: 20220076869
    Abstract: Embodiments of an apparatus that includes a substrate and an inductor residing in the substrate are disclosed. In one embodiment, the inductor is formed as a conductive path that extends from a first terminal to a second terminal. The conductive path has a shape corresponding to a two-dimensional (2D) lobe laid over a three-dimensional (3D) volume. Since the shape of the conductive path corresponds to the 2D lobe laid over a 3D volume, the magnetic field generated by the inductor has magnetic field lines that are predominately destructive outside the inductor and magnetic field lines that are predominately constructive inside the inductor. In this manner, the inductor can maintain a high quality (Q) factor while being placed close to other components.
