Scalable arrays of micro-Penning traps for quantum computing and simulation

Understand

We propose the use of 2-dimensional Penning trap arrays as a scalable platform for quantum simulation and quantum computing with trapped atomic ions.

• This approach involves placing arrays of micro-structured electrodes defining static electric quadrupole sites in a magnetic field, with single ions trapped at each site and coupled to neighbors via the Coulomb interaction.
• We solve for the normal modes of ion motion in such arrays, and derive a generalized multi-ion invariance theorem for stable motion even in the presence of trap imperfections.
• We use these techniques to investigate the feasibility of quantum simulation and quantum computation in fixed ion lattices.
