1. Building a Bosonic Microwave Qubit
Abstract : Superconducting circuits is a promising platform for quantum computing. Quantum information is usually stored in discrete two-level qubits e.g. in transmon qubits. READ MORE

2. Quantum state characterization with deep neural networks
Abstract : In this licentiate thesis, I explain some of the interdisciplinary topics connecting machine learning to quantum physics. The thesis is based on the two appended papers, where deep neural networks were used for the characterization of quantum systems. READ MORE

3. Multi Quanta Relaxation and Nonclassicality of Nonlinear Oscillators
Abstract : The focus of the study is the free quantum evolution of Duffing oscillators which are nonlinearly coupled to bosonic environments. The work evolves from a particular system of an undamped, nonlinear graphene resonator mode to a more generalized framework of oscillator modes interacting with two different configurations of bosonic environments.

4. Digital measurement and control of microwave quantum circuits
Abstract : Superconducting circuits are well established tools for quantum sensing anda promising new platform for quantum computing. Typically these quantumcircuits operate at microwave frequencies where the thermal noise at 10mK in a dilution refrigerator is small compared to the ground-state energy. READ MORE

5. Microwave Gaussian quantum metrology
Abstract : With increasingly sensitive measurements being made possible by technological development, there arises situations where the effects of quantum mechanics have to be taken into account. While quantum mechanics tells us that there are fundamental limits of measurement sensitivity, it also gives us the tools to constructively push the same limits for experimental systems. READ MORE
