One of the possible candidates for a quantum computer is an array of trapped electrons [1]. The traps can be realized with segmented ring electrodes deposited on a planar substrate, combined with a homogeneous magnetic field (Penning traps). Since the first proposal [2], quite a number of additional investigations and studies of this scalable scheme have been performed. Currently some of the elements of this scheme are entering the experimental stage. On the theoretical side, we comment on single qubit coherence, coupling qubits with wires, implementation of Heisenberg spin chains, and quantum networks. Relevant experimental implications are outlined.
