Single electron qubits are attractive for quantum information processing because they offer, for example, the possibility of extremely long coherence times. For scaling up to a large number of coupled qubits, an array of planar Penning traps is a much more promising option than the cylindrical Penning traps within which one-quantum transitions have been observed. This report summarizes optimized trap configurations, discussed at length in Goldman and Gabrielse (Phys Rev A 81:052335, 2010), which promise to make it possible to realize one-electron qubits in a scalable configuration for the first time.
