摘要： A topological qubit wire hosts Majorana zero-energy modes and includes a superconductor, which may be an s-wave superconductor, and a quasi-1D nanowire, which may be a semi-conductor. The Majorana zero-energy modes are localized at ends of the quasi-1D nanowire, which may be sized and shaped to provide occupancy of a few transverse modes in a first direction and occupancy of a few transverse modes in a second direction. In some instances, the occupancy in the first direction may be greater than or equal to 3, and the occupancy in the second direction may be 1.

摘要： A detector includes a voltage source for providing a bias voltage and first and second non-insulating layers, which are spaced apart such that the bias voltage can be applied therebetween and form an antenna for receiving electromagnetic radiation and directing it to a specific location within the detector. The detector also includes an arrangement serving as a transport of electrons, including tunneling, between and to the first and second non-insulating layers when electromagnetic radiation is received at the antenna. The arrangement includes a first insulating layer and a second layer configured such that using only the first insulating in the arrangement would result in a given value of nonlinearity in the transport of electrons while the inclusion of the second layer increases the nonlinearity above the given value. A portion of the electromagnetic radiation incident on the antenna is converted to an electrical signal at an output.

摘要： A normal-insulator-superconductor (NIS) microrefrigerator in which a superconducting single crystal is both the substrate and the superconducting electrode of the NIS junction. The refrigerator consists of a large ultra-pure superconducting single crystal and a normal metal layer on top of the superconducting crystal, separated by a thin insulating layer. The superconducting crystal can be either cut from bulk material or grown as a thick epitaxial film. The large single superconducting crystal allows quasiparticles created in the superconducting crystal to easily diffuse away from the NIS junction through the lattice structure of the crystal to normal metal traps to prevent the quasiparticles from returning across the NIS junction. In comparison to thin film NIS refrigerators, the invention provides orders of magnitude larger cooling power than thin film microrefrigerators. The superconducting crystal can serve as the superconducting electrode for multiple NIS junctions to provide an array of microrefrigerators. The normal electrode can be extended and supported by microsupports to provide support and cooling of sensors or arrays of sensors.

摘要： A method is described for forming a solid state qubit. The method includes forming a dot or an anti-dot. The dot or anti-dot can be formed on a substrate and is delimited by an interface that defines a closed area. The dot or anti-dot includes a superconductive material with Cooper pairs that are in a state of non-zero orbital angular momentum on at least one side of the interface. The method includes removing superconducting material on the inner side of the interface or removing the outer side of the interface by etching. The method can further include forming a dot or an anti-dot by damaging the superconducting material such that the superconductive material becomes non-superconductive in predefined areas. The damaging of superconducting material can be performed by irradiation with particles, such as alpha particles or neutrons. The superconductive material can also be formed by doping a non-superconductive material.

摘要： The present invention introduces a detector that is able to detect single microwave photons propagating in a waveguide. The waveguide of the invention is lowered to a temperature where it becomes superconductive. Disposed between a middle wire and a ground plane of the waveguide is a very small piece of a desired normal metal, whereby so-called SN contacts are formed between these materials. A separate reflection measurement circuit is coupled to the normal metal piece. When the impedance of the waveguide is matched to the impedance of the normal metal piece as well as possible, a photon propagating in the waveguide is most likely absorbed in the normal metal. The absorption slightly raises the temperature of the piece, which further changes the impedance observed in a so-called SIN junction between the reflection measurement circuit and the piece. The changed amplitude and phase are detectable at the outlet obtained from a mixer of the reflection measurement circuit, whereby a single absorbed photon can be detected. In principle, the present method and device enable quantum calculation in view of future applications.

摘要： A detector (10A) for detecting electromagnetic radiation incident thereon over a desired range of frequencies exhibits a given responsivity and includes an output and first and second non-insulating layers (14), which layers are spaced apart such that a given voltage can be applied thereacross. The first non-insulating layer (12) is formed of a metal, and the first and second non-insulating layers are configured to form an antenna structure for receiving electromagnetic radiation over the desired range of frequencies. The detector further includes an arrangement disposed between the first and second non-insulating layers and configured to serve as a transport of electrons between the first and second non-insulating layers as a result of the electromagnetic radiation being received at the antenna structure. The arrangement includes at least a first layer of an amorphous material (16) such that the transport of electrons includes, at least in part, transport by means of resonant tunneling, and such that at least a portion of the electromagnetic radiation incident on the antenna is converted at the output to an electrical signal having an intensity which depends on the given responsivity.
