Query: Suppression of Hyperfine Dephasing by Spatial Exchange of Double Quantum
  Dots   We examine the logical qubit system of a pair of electron spins in double
quantum dots. Each electron experiences a different hyperfine interaction with
the local nuclei of the lattice, leading to a relative phase difference, and
thus decoherence. Methods such as nuclei polarization, state narrowing, and
spin-echo pulses have been proposed to delay decoherence. Instead we propose to
suppress hyperfine dephasing by adiabatic rotation of the dots in real space,
leading to the same average hyperfine interaction. We show that the additional
effects due to the motion in the presence of spin-orbit coupling are still
smaller than the hyperfine interaction, and result in an infidelity below
10^{-4} after ten decoupling cycles. We discuss a possible experimental setup
and physical constraints for this proposal.
