Superconducting Quantum Information Processors: Coherence, Control and Quantum Spectroscopy
Antonio D’Arrigo, Elisabetta Paladino, G. Falci · 2009
Solid-state implementations of quantum bits are very promising for quantum computation, because of their potential scalability and integrability. On the other side solid state noise represents a serious limitation towards the target of solid state quantum computation. We illustrate various possibilities to apply quantum control techniques to solid state qubits. We focus on open loop quantum control, and show that a simple closed loop protocol can greatly improve the coherence time of single qubit gates.
