  • Transmon qubits with self defined junctions
    Patent number: 11094873
    Abstract: A method of making a Josephson junction in a superconducting qubit includes providing a substrate having a convex structure with a first face and a second face meeting at an edge; depositing a first layer of superconducting material on the first face; oxidizing the first layer to form a layer of oxide material on a surface of the first layer; and depositing a second layer of the superconducting material on the second face. A portion of the second layer is in contact with a portion of the layer of oxide material at or in the vicinity of the edge such that the portion of the layer of oxide material is sandwiched between a portion of the first layer and the portion of the second layer to define a Josephson junction at or in the vicinity of the edge.
    Type: Grant
    Filed: November 14, 2019
    Date of Patent: August 17, 2021
    Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION

  • Optical fiber probe tips and methods for fabricating same
    Patent number: 7933482
    Abstract: Optical fiber probe tips and methods for fabricating the same are presented. One method entails immersing a distal end of an optical fiber having a cladding and a core into an etching solution and simultaneously etching the cladding and the core using the etching solution for tapering the cladding and the core to form a tapered cladding and a tapered core tip. The optical fiber probe tips are suitable for near-field, scanning, optical microscopy (NSOM).
