1. Controllable coupling of superconducting qubits and implementation of quantum gate protocols
Sammanfattning : The concept of a quantum computer was invented in the beginning of the 1980s as a quantum generalization of the reversible classical computer. After discoveries in the middle of the 1990s of quantum algorithms, which wouldsolve some problems considered intractable for classical computers, the field of quantum computing has developed rapidly.

2. Strong Interaction Between a Single Artificial Atom and Propagating Microwave Photons
Sammanfattning : The realization of a quantum network composed of quantum nodes which process quantum fields and quantum channels to transfer quantum information has recently been proposed. In recent years, fundamental experiments produced by superconducting circuits suggest that they are promising candidates for realization of a quantum network. LÄS MER
3. Fast-tunable resonators and quantum electrical circuits
Sammanfattning : In this thesis, measurements on superconducting electrical circuits that exhibit quantum mechanical effects are presented. Nonlinear superconducting circuits can be regarded as artificial atoms with energy spectra that can be engineered. The artificial atoms can be used as quantum bits for quantum computation. LÄS MER
4. Effects of the environment on quantum systems: decoherence, bound states and high impedance in superconducting circuits
Sammanfattning : Superconducting circuits in the quantum regime represent a viable platform for microwave quantum optics, quantum simulations and quantum computing. In the last two decades, a large effort brought this architecture from an academic curiosity to concrete technology. LÄS MER
5. The Josephson parametric oscillator - From microscopic studies to single-shot qubit readout
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
