摘要: An electronic device includes a first superconducting wire (with a first end and a second end) having a first threshold superconducting current. The device includes a second superconducting wire (with a first end and a second end) having a second threshold superconducting current that is less than the first threshold superconducting current. The second end of the first superconducting wire and the second end of the second superconducting wire are coupled to a common voltage node. A resistor is coupled between the first superconducting wire and the second superconducting wire, with a first end of the resistor coupled to the first end of the first superconducting wire and a second end of the resistor coupled to the first end of the second superconducting wire. The device includes a current source coupled with the first superconducting wire, and coupled with a combination of the resistor and the second superconducting wire.

摘要: A superconductor device is manufactured by depositing a barrier layer over a substrate including silicon, the barrier layer including silicon and nitrogen; depositing a seed layer for a superconductor layer over the barrier layer, the seed layer including aluminum and nitrogen; depositing the superconductor layer over the seed layer, the superconductor layer including a layer of a superconductor material, the barrier layer serving as an oxidation barrier between the layer superconductor material and the substrate; and depositing a silicon cap layer over the superconductor layer. In some embodiments, the superconductor device includes a waveguide and a metal contact at a sufficient distance from the waveguide to prevent optical coupling between the metal contact and the waveguide.

摘要: A method includes receiving input light having an input wavelength in a first optical resonator for causing resonance of the input light in the first optical resonator. The first optical resonator includes a non-linear optical medium. The method also includes converting at least a portion of the input light to a combination of first output light having a first output wavelength that is different from the input wavelength and second output light having a second output wavelength that is different from the input wavelength and the first output wavelength by passing the input light through the non-linear optical medium. The method further includes causing resonance of the first output light and the second output light in a second optical resonator. A portion of the first optical resonator is coupled to a portion of the second optical resonator.

摘要: An example single photon detector includes a thin sheet of superconducting material connected to a current source to receive a small current generated from detection one or more photons, the thin sheet of superconducting material connected to a ground, the thin sheet of superconducting material further connected to an amplifying current source to receive a larger current that is larger than the small current. The example detector further includes an asymmetric arrangement of nanowires, the asymmetric arrangement of nanowires comprising three or more differently sized nanowires that are arranged in the thin sheet in a sequence from smallest to largest such that the asymmetric arrangement of nanowires are triggered in the sequence in response to the small current. The example detector also includes an output to output current from the amplifying current source in response to the asymmetric arrangement of nanowires being triggered.

摘要: A system includes a plurality of superconducting wires connected in parallel with one another. The plurality of superconducting wires includes a first superconducting wire and a second superconducting wire. The plurality of superconducting wires are configured to, while receiving a bias current provided to the parallel combination of the plurality of superconducting wires, operate in a superconducting state in the absence of a trigger current. The first superconducting wire is configured to, while receiving the bias current, transition to a non-superconducting state in response to receiving the trigger current. The second superconducting wire is configured to, while receiving the bias current, transition to a non-superconducting state in response to the first superconducting wire transitioning to the non-superconducting state.

摘要: An electronic device (e.g., a diode) is provided that includes a substrate and a patterned layer of superconducting material disposed over the substrate. The patterned layer forms a first electrode, a second electrode, and a loop coupling the first electrode with the second electrode by a first channel and a second channel. The first channel and the second channel have different minimum widths. For a range of current magnitudes, when a magnetic field is applied to the patterned layer of superconducting material, the conductance from the first electrode to the second electrode is greater than the conductance from the second electrode to the first electrode.

摘要: A system includes a first superconducting wire and a second superconducting wire connected in parallel. The system includes a first current source coupled to the first superconducting wire and configured to supply a first current in response to a trigger event. The system includes a second current source coupled in series with the parallel combination of the first superconducting wire and the second superconducting wire and configured to supply a second current. The superconducting wires are configured to, while receiving the second current, operate in a superconducting state in the absence of the first current. The first superconducting wire is configured to, while receiving the second current, transition to a non-superconducting state in response to the first current. The second superconducting wire is configured to, while receiving the second current, transition to a non-superconducting state in response to the first superconducting wire transitioning to the non-superconducting state.
