| Abstract: | We show how to control and perform universal three-qubit quantum computation with trapped electron quantum states. The three
qubits are the electron spin, and the first two quantum states of the cyclotron and axial harmonic oscillators. We explicitly
show how universal three-qubit gates can be performed. As an example of a quantum algorithm, we outline the implementation
of the three-qubit Deutsch-Jozsa algorithm in this system.
