Trapped electrons in vacuum for a scalable quantum processor
Giacomo Ciaramicoli, Irene Marzoli, P. Tombesi · Physical Review A · 2004
We describe in detail a theoretical scheme to trap and manipulate an arbitrary number of electrons in vacuum for universal quantum computation. The particles are confined in a linear array of Penning traps by means of a combination of static electric and magnetic fields. Two-electron operations are realized by controlling the Coulomb interaction between neighboring particles. The performances of such a device are evaluated in terms of clock speed, fidelity, and decoherence rates.
