Decoherence, control, and encoding of coupled solid-state quantum bits

In this thesis the decoherence properties, gate performance,
control of solid-state quantum bits (qubits), and novel design
proposals for solid-state qubits analogous to quantum optics are
investigated. The qubits are realized as superconducting
nanocircuits or quantum dot systems. The thesis elucidates both
very appealing basic questions, like the generation and detection
of deeply nonclassical states of the electromagnetic field, i.e.,
single photon Fock states, in the solid-state, but also presents a
broad range of different strategies to improve the scalability and
decoherence properties of solid-state qubit setups.
