Ion trap nuclear resonance on $\mathsf{^{151}Eu^ + }$

2003

Laser-microwave double resonance techniques applied to a cloud of a natural mixture of Eu + isotopes confined in a Penning trap has been used to induce and detect nuclear Zeeman transitions. In spite of the complex level structure of Eu + and overlapping spectra from the two isotopes five different $\Delta m_I = 1$ transitions could be observed from which the nuclear magnetic moment can be derived. We obtain for 151 Eu + g I = 1.377 34(6) demonstrating the potential for high accuracy of the technique. The experiment can be considered as a feasibility test that precise spectroscopy data using the ion storage technique can be obtained of very complex ions and under unfavourable conditions.

Experimental and theoretical challenges for the trapped electron quantum computer

2009

We discuss quantum information processing with trapped electrons. After recalling the operation principle of planar Penning traps we sketch the experimental conditions to load, cool and detect single electrons. Here we present a detailed investigation of a scalable scheme including feasibility studies and the analysis of all important elements, relevant for the experimental stage. On the theoretical side, we discuss different methods to couple electron qubits. We estimate the relevant qubit coherence times and draw implications for the experimental setting. A critical assessment of quantum information processing with trapped electrons is concluding the article.
