We show how building blocks demonstrated with one trapped electron might be used to make a model system and method for entangling two electrons. Applications are then considered, including two-qubit gates and more precise quantum metrology protocols.engjournal articlehttp://doi.org/10.1103/PhysRevA.81.022301https://journals.aps.orgopen access53Quantum limitStatesIonFísica (Física)22 Física
