  1. 1. Engineering superconducting qubits : towards a quantum machine

    Författare :Joachim Sjöstrand; Anders Karlhede; Denis Vion; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : A quantum computer is an information processing machine, much like an ordinary classical computer, but its function is based on quantum mechanical principles. To be able to construct such a machine would be a fantastic accomplishment---to have total control over a quantum system is a dream for both physicists and science-fiction enthusiasts. LÄS MER

  3. 2. Pulse and hold switching current readout of superconducting quantum circuits

    Författare :Jochen Walter; David Haviland; Hans Mooij; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson junction; readout; qubit; detector; frequency dependent damping; quantronium; phase-space; correlation analysis; Physics; Fysik;

    Sammanfattning : Josephson junction qubits are promising candidates for a scalable quantum processor. Such qubits are commonly manipulated by means of sequences of rf-pulses and different methods are used to determine their quantum state. LÄS MER

  4. 3. NbTiN for improved superconducting detectors

    Författare :Julien Zichi; Val Zwiller; Gregory Gol'tsman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superconducting nanowire sngle photon detector; SNSPD; niobium titanium nitride; NbTiN; reactive co-sputtering; quantum communications; quantum sensing; Fysik; Physics;

    Sammanfattning : The physics of single photons is fascinating, by manipulating them we can observe and probe quantum effects. Doing so requires the fabrication and utilization of single photon sources, of which many types have been developed including quantum dots, trapped atoms and ions, and color centers. LÄS MER

  5. 4. Quantum optics in superconducting circuits : Generating, engineering and detecting microwave photons

    Författare :Sankar Raman Sathyamoorthy; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; single photon source; superconducting circuits; single photon detector; cross-Kerr effect; Quantum optics; circuit QED;

    Sammanfattning : Quantum optics in superconducting circuits, known as circuit QED, studies the interaction of photons at microwave frequencies with artificial atoms made of Josephson junctions. Although quite young, remarkable progress has been made in this field over the past decade, especially given the interest in building a quantum computer using superconducting circuits. LÄS MER

  7. 5. A Central Rapidity Straw Tracker and Measurements on Cryogenic Components for the Large Hadron Collider

    Författare :Hans Danielsson; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical instrumentation; tracker; transsition radiation; LHC; cryogenics; superconducting; Metrology; helium; Metrologi; fysisk instrumentering; Fysicumarkivet A:1997:Danielsson; Fysicumarkivet A:1997:Danielsson;

    Sammanfattning : This thesis is divided into two parts in which two different aspects of the Large Hadron Collider (LHC) Project are discussed. The first part describes the design of a transition radiation tracker (TRT) for the inner detector in ATLAS. In particular, the barrel part was studied in detail. The barrel TRT consists of 52 544 1.
