Realistic Theory of Solid-State Qubits
Abstract
We have studied quantum coherence and control in solid-state qubits, mostly in superconductors. We have outlined several strategies to obtain high-fidelity quantum logic gates in the presence of decoherence. We have studied realistic, structured environments to qubits, including environments with resonances, slow noise, and non-Markovian effects. In all cases, we have formulated strategies how to master and engineer the decoherence properties. We have analyzed examples from superconducting charge and flux qubits as well as quantum dots.
