Towards Trapping Electrons in Paul Traps for Quantum Computing

Trapped-electron qubits provide an interesting alternative to trapped ions in quantum information processing. The operations on trapped electron systems can be all-electronic, making it easier to scale up, and the light mass of electrons enables faster two-qubit gates. In order to evaluate the feasibility of a trapped electron quantum computer, we simulate the electron dynamics inside Paul traps with a drive frequency of 1.5 GHz. From the simulations, we determine the trap depth and explore the validity of pseudopotential approximation. In addition to the electron dynamics in the trapping potential, we also explore how to deterministically eject electrons from the trapping potential towards a particle detector.
