Feasibility study of quantum computing using trapped electrons



Qian Yu, Alberto Alonso, Jackie Caminiti, Robert Sutherland, Dietrich Leibfried, Kayla Rodriguez, Madhav Dhital, Boerge Hemmerling, Hartmut Haeffner, Kristin Beck


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 multiqubit gate operations. Numeric simulations indicate that two-qubit Bell-state delities of order 99.99% can be achieved assuming reasonable experimental parameters.
