The building block is a superconducting qubit coupled with a solid-state resonator. We study decoherence, discuss rules for environment engineering and analyze working conditions where a high degree of protection from phase errors is achieved. We review some of the protocols which have been recently proposed for studying entanglement in the solid state.

For this pourpose we have investigated several families of extremal mixed states by exploiting 2-photon polarization correlations.

We show that low-resolution measurements can fail to catch quantum properties, and demonstrate the effectiveness of a hybrid discrete-continuous variable approach in a microscopic-...
