Superconducting Quantum Information Processors: Coherence, Control and Quantum Spectroscopy
Giuseppe Falci, Elisabetta Paladino, D'Arrigo
A second generation of Superconducting Quantum Information Processors showing nowadays single qubit quality factors of hundreds, are resilient to solid-state noise up to hundreds MHz.
Quantum control techniques may be applied to achieve dynamical decoupling, Closed loop protocols are expected to increase the initial amplitude of the output signal. Advanced control techniques, while providing dynamical protection from environmental noise can be used as a tool for quantum noise spectroscopy in the mesoscopic regime.
