Decoherence induced by anisotropic hyperfine interaction in Si spin qubits
Decoherence induced by anisotropic hyperfine interaction in Si spin qubits
We study Si:P donor electron spin decoherence due to anisotropic hyperfine (AHF) interaction with the surrounding nuclear spin bath. In particular, we clarify the electron spin echo envelope modulation (ESEEM) in the Si:P system and the resonancelike contributions from nuclear spins in various shells away from the P atoms. We …
