Patent number: 10562765Abstract: A novel and useful controlled quantum shift register for transporting particles from one quantum dot to another in a quantum structure. The shift register incorporates a succession of qdots with tunneling paths and control gates. Applying appropriate control signals to the control gates, a particle or a split quantum state is made to travel along the shift register. The shift register also includes ancillary double interaction where two pairs of quantum dots provide an ancillary function where the quantum state of one pair is replicated in the second pair. The shift register also provides bifurcation where an access path is split into two or more paths. Depending on the control pulse signals applied, quantum dots are extended into multiple paths. Control of the shift register is provided by electric control pulses. An optional auxiliary magnetic field provides additional control of the shift register.Type: GrantFiled: June 19, 2019Date of Patent: February 18, 2020Assignee: Equal1.Labs Inc.Inventors: Dirk Robert Walter Leipold, George Adrian Maxim, Michael Albert Asker

Publication number: 20200003925Abstract: A novel and useful multistage semiconductor quantum detector circuit incorporating an anticorrelation mechanism. The quantum structure has at least the first stage sensor of the detector merged into the quantum structure in order to minimize loading of the quantum structure. The merged quantum structure and detector sensor may be encapsulated in a metal cage in order to provide enhanced rejection of the environmental parasitic electric and/or magnetic fields. A double boot strapping detector front-end configuration substantially eliminates the loading coming from both the gate-source and the gate-drain parasitic capacitances of the first sensor device of the detector that is connected to the quantum structure. In addition, differential detection aids in rejecting leakage, noise, and correlated interference coupling. Both dummy referenced differential detection as well as self-referenced differential detection may be employed in the detector.Type: ApplicationFiled: September 12, 2019Publication date: January 2, 2020Applicant: equal1.labs Inc.Inventors: Dirk Robert Walter Leipold, George Adrian Maxim, Michael Albert Asker

Publication number: 20190392338Abstract: 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.Type: ApplicationFiled: June 19, 2019Publication date: December 26, 2019Applicant: equal1.labs Inc.Inventors: Dirk Robert Walter Leipold, George Adrian Maxim, Michael Albert Asker

Publication number: 20190392341Abstract: 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.Type: ApplicationFiled: June 19, 2019Publication date: December 26, 2019Applicant: equal1.labs Inc.Inventors: Dirk Robert Walter Leipold, George Adrian Maxim, Michael Albert Asker

Publication number: 20190392336Abstract: 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.Type: ApplicationFiled: June 19, 2019Publication date: December 26, 2019Applicant: equal1.labs Inc.Inventors: Dirk Robert Walter Leipold, George Adrian Maxim, Michael Albert Asker

Publication number: 20190393400Abstract: 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.Type: ApplicationFiled: June 19, 2019Publication date: December 26, 2019Applicant: equal1.labs Inc.Inventors: Dirk Robert Walter Leipold, George Adrian Maxim, Michael Albert Asker
