摘要： A within-chip magnetic field control device is formed in proximity to a Josephson Junction (JJ) structure. The within-chip magnetic field control device includes wiring structures that are located laterally adjacent to the JJ structure. In some embodiments, the magnetic field control device also includes, in addition to the wiring structures, a conductive plate that is connected to the wiring structures and is located beneath the JJ structure. Use of electrical current through the wiring structures induces, either directly or indirectly, a magnetic field into the JJ structure. The strength of the field can be modulated by the amount of current passing through the wiring structures. The magnetic field can be turned off as needed by ceasing to allow current to flow through the wiring structures.

摘要： Techniques are disclosed for fabricating and using a neuromorphic computing device including biological neurons. For example, a method for fabricating a neuromorphic computing device includes forming a channel in a first substrate and forming at least one sensor in a second substrate. At least a portion of the channel in the first substrate is seeded with a biological neuron growth material. The second substrate is attached to the first substrate such that the at least one sensor is proximate to the biological neuron growth material and growth of the seeded biological neuron growth material is stimulated to grow a neuron in the at least a portion of the channel.

摘要： A method of producing a quantum circuit includes forming a mask on a substrate to cover a first portion of the substrate, implanting a second portion of the substrate with ions, and removing the mask, thereby providing a nanowire. The method further includes forming a first lead and a second lead, the first lead and the second lead each partially overlapping the nanowire. In operation, a portion of the nanowire between the first and second leads forms a quantum dot, thereby providing a quantum dot Josephson junction. The method further includes forming a third lead and a fourth lead, one of the third and fourth leads partially overlapping the nanowire, wherein the third lead is separated from the fourth lead by a dielectric layer, thereby providing a Dolan bridge Josephson junction. The nanowire is configured to connect the quantum dot Josephson junction and the Dolan bridge Josephson junction in series.

摘要： Methods and systems for regulating supply voltage is described. In an example, a device can receive unregulated supply. The device can be connected to a ring oscillator and an integrated circuit. The device can be configured to regulate the unregulated supply to a first voltage. The device can be further configured to provide the regulated supply to the ring oscillator, where the ring oscillator operates with the regulated supply. The device can be further configured to, in response to a change in the regulated supply from the first voltage to a second voltage, adjust the changed regulated supply to return to the first voltage to cause the ring oscillator to operate with a constant regulated supply having the first voltage.
