  • Publication number: 20240349628
    Abstract: A semiconductor-superconductor hybrid device comprises a semiconductor component configured to host a 2DEG or a 2DHG; a superconductor component for inducing superconductivity in a channel of the semiconductor component; and a set of depletion gates. The superconductor component comprises a grounded strip of superconductor. The depletion gates comprise a first outer gate for defining a first outer segment; a second outer gate for defining a second outer segment, and an inner gate for defining an inner segment of the channel. The device further comprises a first junction comprising a space between the first outer gate and the inner gate, and a helper gate for gating the first space; and a second junction comprising a space between the second outer gate and the inner gate, and a helper gate for gating the second space. The helper gates are operable to connect the channel to leads.

  • Patent number: 12082512
    Abstract: A semiconductor-superconductor hybrid device comprises a semiconductor layer and a superconductor layer. The superconductor layer is arranged over an edge of the semiconductor layer so as to enable energy level hybridisation between the semiconductor layer and the superconductor layer. The semiconductor layer is arranged in a sandwich structure between first and second insulating layers, each insulating layer being in contact with a respective opposed face of the semiconductor layer. This configuration may allow for good control over the geometry of the semiconductor layer and may improve tolerance to manufacturing variations. The device may be useful in a quantum computer. Also provided is a method of manufacturing the device, and a method of inducing topological behaviour in the device.

  • Publication number: 20240292761
    Abstract: A semiconductor-superconductor hybrid device comprises a semiconductor, a superconductor, and a barrier between the superconductor and the semiconductor. The device is configured to enable energy level hybridisation between the semiconductor and the superconductor. The barrier is configured to increase a topological gap of the device. The barrier allows for control over the degree of hybridisation between the semiconductor and the superconductor. Further aspects provide a quantum computer comprising the device, a method of manufacturing the device, and a method of inducing topological behaviour in the device.

  • Publication number: 20240074330
    Abstract: Topological superconductor devices with gates formed in two gate layers are described. A topological superconductor device includes a superconducting wire having a first junction near a first end of the superconducting wire and a second junction near a second end, opposite to the first end. The topological superconductor device further includes: (1) a first side-plunger gate and a second-side plunger gate formed in a first gate layer of the topological superconductor device, (2) a middle-plunger gate formed in the first gate layer of the topological superconductor device, (3) a first cutter gate formed in a second layer, different from the first layer, of the topological superconductor device, and (4) a second cutter gate formed in the second layer of the topological superconductor device. The plunger gates are operable to tune respective sections of the superconducting wire and the cutter gates are operable to open and close the respective junctions.
