2. 1. Waveguide Quantum Electrodynamics in Superconducting Circuits

   Author : Emely Wiegand; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Superconducting Qubits; Artificial Atoms; Waveguide Quantum Electrodynamics; Circuit Quantum Electrodynamics; Quantum Optics;

   Abstract : In the last two decades, the field of circuit quantum electrodynamics, that studies the interaction between superconducting qubits and 1-dimensional waveguides, has been of great interest. It provides a great potential to build quantum devices, which are important for quantum computing, quantum communication and quantum information. READ MORE

4. 2. Quantum Optics and Waveguide Quantum Electrodynamics in Superconducting Circuits

   Author : Emely Wiegand; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Quantum Optics; Circuit Quantum Electrodynamics; Waveguide Quantum Electrodynamics; Superconducting Qubits; Artificial Atoms;

   Abstract : Waveguide circuit quantum electrodynamics (waveguide circuit QED) studies light-matter interaction with superconducting circuits in one dimension. In circuit QED, natural atoms are replaced by superconducting qubits consisting of a non-linear Josephson junction, resulting in an anharmonic energy spectrum just like real atoms. READ MORE

5. 3. Theoretical quantum optics with giant atoms

   Author : Ariadna Soro Álvarez; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; continuous waveguides; master equation; artificial atoms; structured waveguides; Quantum optics; waveguide quantum electrodynamics; resolvent formalism; SLH formalism; giant atoms; open quantum systems;

   Abstract : Giant atoms have emerged as new paradigm in quantum optics during the last decade. These are quantum emitters that couple to light—or other bosonic fields—at multiple discrete points, which can be spaced wavelengths apart. READ MORE

6. 4. 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

7. 5. 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).
