Dynamic Nuclear Polarization with Single Electron Spins
J. R. Petta, J. M. Taylor, A. C. Johnson +5
We polarize nuclear spins in a GaAs double quantum dot by controlling two-electron spin states near the anti-crossing of the singlet (S) and m_S=+1 triplet (T+) using pulsed gates.…
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…
Singlet-triplet spin blockade and charge sensing in a few-electron double quantum dot
A. C. Johnson, J. R. Petta, C. M. Marcus +2
Singlet-triplet spin blockade in a few-electron lateral double quantum dot is investigated using simultaneous transport and charge-sensing measurements. Transport from the (1,1) to…
Cotunneling Spectroscopy in Few-Electron Quantum Dots
D. M. Zumbuhl, C. M. Marcus, M. P. Hanson +1
Few-electron quantum dots are investigated in the regime of strong tunneling to the leads. Inelastic cotunneling is used to measure the two-electron singlet-triplet splitting above…
Spin and Polarized Current from Coulomb Blockaded Quantum Dots
R. M. Potok, J. A. Folk, C. M. Marcus +3
We report measurements of spin transitions for GaAs quantum dots in the Coulomb blockade regime, and compare ground and excited state transport spectroscopy to direct measurements…
