  2. 6. High-Tc SQUIDs for magnetophysiology - development of a magnetometer system and measurements of evoked fields from hippocampal neurons in vitro

    Author : Per Magnelind; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neuromagnetism; brain slice; neurophysiology; electrophysiology; hippocampus; biomagnetism; SQUID;

    Abstract : This thesis concerns development of a system based on a high-transition-temperature superconducting quantum interference device (high-Tc SQUID) magnetometer. The system has been designed and used for magnetic field recordings from brain slices, i.e. magnetophysiology. READ MORE

  4. 7. Nonlinear dynamics of Josephson Junction Chains and Superconducting Resonators

    Author : Adem Ergül; David B. Haviland; Per Delsing; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Josephson Junction; SQUID; Superconducting Resonators;

    Abstract : This thesis presents the results of the experimental studies on two kindof Superconducting circuits: one-dimensional Josephson junction chains andsuperconducting coplanar waveguide (CPW) resonators. One-dimensionalJosephson junction chains are constructed by connecting many Superconducting quantum interference devices (SQUIDs) in series. READ MORE

  5. 8. Parametrically pumped superconducting circuits

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

    Abstract : In this licentiate thesis, I present the design, fabrication, and characterization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators (~5 GHz), terminated at one end by a non-linear inductance provided by a SQUID (superconducting quantum interference device).

  6. 9. Studies of triggering and exotic particle searches at ATLAS, and a search for trapped monopoles

    Author : Katarina Bendtz; David Milstead; Chad Finley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic monopoles; ATLAS; SQUID; trigger; exotic particles; heavy long-lived particles; High Energy Physics; högenergifysik;

    Abstract : The ATLAS detector at the LHC operated through 2011 and 2012 with 7 and 8 TeV centre-of-mass energy of its colliding proton bunches, respectively. One if its main objectives is to search for physics beyond the Standard Model. READ MORE

  7. 10. The Josephson parametric oscillator - From microscopic studies to single-shot qubit readout

    Author : Philip Krantz; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
