Abstract: Quantum computing systems require methods to control energies of qubits and couplers for quantum operations. Flux biasing of qubits and quantum couplers is provided for a superconducting quantum computer using single-flux-quantum (SFQ) technology. This method is applicable to a wide range of superconducting qubit structures and couplers, including transmons, fluxoniums, flux qubits, phase qubits and other superconducting qubits. This method enables arbitrary-amplitude time-varying flux biasing of qubits and couplers, due to a sequence of high-speed SFQ pulses. Several preferred embodiments are disclosed which provide high-fidelity control of fast single-qubit and multi-qubit operations.

Abstract: A method of controlling a handheld vacuum cleaner (10) having a fluid flow path extending from a dirty air inlet (14) to a clean air outlet (18) is provided. The method includes measuring a pressure value of an airflow through the fluid flow path, and determining whether the pressure value exceeds a predetermined threshold, which is indicative of a clog within the fluid flow path. The method further includes alerting a user of the handheld vacuum cleaner (10) when the pressure value exceeds the predetermined threshold. Alerting the user includes transmitting an alert to a personal device (418) of the user and identifying to the user a plurality of possible clog locations along the fluid flow path.

Abstract: A method of using an upright vacuum cleaner includes positioning a floor nozzle on a surface to be cleaned, measuring a first characteristic of a brushroll motor with a first sensor, and communicating the first characteristic with a controller. The method also includes comparing the first characteristic with a first threshold value stored by the controller, which is associated with determining if the floor nozzle is on a first cleaning surface or a second cleaning surface. The method further includes changing a suction motor between a first mode when feedback received by the first sensor is greater than the first threshold value, and a second mode when feedback received by the first sensor is less than the first threshold value. The method also includes operating the suction motor at a first speed while in the first mode, and at a second speed while in the second mode.
