Effect of Exchange Interaction on Spin Dephasing in a Double Quantum Dot
E. A. Laird, J. R. Petta, A. C. Johnson +4
We measure singlet-triplet dephasing in a two-electron double quantum dot in the presence of an exchange interaction which can be electrically tuned from much smaller to much large…

Solid-state circuit for spin entanglement generation and purification
J. M. Taylor, W. Dür, P. Zoller +3
We show how realistic charge manipulation and measurement techniques, combined with the exchange interaction, allow for the robust generation and purification of four-particle spin…
