Abstract: A quantum-computing method includes executing a data quantum circuit with data qubits, all of which are of the same first type of quantum system having a first plurality of transitions. The quantum-computing method also includes executing a spectator quantum circuit with spectator qubits, all of which are of the same second type of quantum system having a second plurality of transitions. During execution of the spectator and data quantum circuits, the spectator qubits and data qubits are simultaneously driven with a coherent radiation field while the data qubits are in coherent superposition states. The radiation field is (i) far detuned from all of the first plurality of transitions and (ii) resonant with one of the second plurality of transitions. The first and second types of quantum system may be two different atomic species that can each be laser cooled and trapped, such as rubidium and cesium.

Abstract: A system for individually controlling a plurality of qubits in an atom array includes a plurality of optical modulators and a fiber array having a plurality of optical fibers. Each of the optical fibers has an fiber input coupled to a modulator output of a respective one of the optical modulators. The system also includes a lens configured to image the output of the fiber array onto the qubits such that an fiber output of each of the optical fibers is imaged onto a respective one of the qubits. The lens may be a microscope objective. The system may also include a splitter that splits a single laser beam into a plurality of modulator-input beams such that each of the modulator-input beams is coupled to a respective one of the optical modulators. Each optical modulator may include an acousto-optic modulator, electro-optic modulator, mechanical shutter, or other optical component.

Abstract: A control system for a vehicle uses one or more inputs of a velocity request, a brake request, a speed request, travel direction indication, engine speed, and vehicle speed to determine a control strategy for a continuously variable transmission. A target engine speed is selected based upon the inputs, and the engine and continuously variable transmission ratio are controlled to achieve the target engine speed while controlling the vehicle according to the inputs. In some embodiments, the control strategy further selects the target engine speed according to accessory system demands, such as a hoist or lift system.
