Figure 1From: Universal set of quantum gates for the flip-flop qubit in the presence of 1/f noiseScheme of the flip-flop qubit. A donor atom of 31P is embedded in a bulk of 28Si at a distance d from the Si/SiO2 interface. The metal gate controls through an electric field \(E_{z}\) the electron position between the nucleus (\(|d\rangle \)) and the interface (\(|i \rangle \)) with the dielectric. A constant magnetic field \(B_{0}\) is also appliedBack to article page
