  1. 11. The Josephson parametric oscillator - From microscopic studies to single-shot qubit readout

    Författare :Philip Krantz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; resonators; Superconducting circuits; parametric oscillators; quantum bit; quantum information; SQUID; pumpistor; Josephson junction; circuit quantum electrodynamics;

    Sammanfattning : Circuit quantum electrodynamics (cQED) is a prominent platform for quantum information processing, in which microwave photons are confined into resonant cavities coupled to superconducting quantum bits (qubits). The large effective dipole moment of the qubit, in combination with the high energy density of the quasi 1-D resonator allow these systems to enter the so-called strong coupling regime. LÄS MER

  5. 15. Charging effects in small capacitance Josephson junction circuits

    Författare :Peter Ågren; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis describes fabrication, measurements and analysisof two different Josephson junction circuits; the Cooper pairtransistor (CPT) and the one dimensional Josephson junctionarray (JJA). All experiments are conducted in a dilutionrefrigerator with a base temperature of 15{30 mK. LÄS MER
