  We investigate the feasibility of using electrons in a linear Paul trap as
qubits in a future quantum computer. We discuss the necessary experimental
steps to realize such a device through a concrete design proposal, including
trapping, cooling, electronic detection, spin readout and single and
multi-qubit gate operations. Numeric simulations indicate that two-qubit
Bell-state fidelities of order 99.99% can be achieved assuming reasonable
experimental parameters.
