Robust entanglement by continuous dynamical decoupling of the J-coupling interaction

We propose a σ _z ⊗ σ _z laser-free entangling gate which uses the intrinsic J -coupling of ions in a static magnetic gradient. Dephasing of the interaction is suppressed by means of continuous dynamical decoupling using pairs of microwave fields. The gate is virtually insensitive to common amplitud...
