Qubit protection in nuclear-spin quantum dot memories
Z. Kurucz, M. W. Sørensen, J. M. Taylor +2
We present a mechanism to protect quantum information stored in an ensemble of nuclear spins in a semiconductor quantum dot. When the dot is charged the nuclei interact with the sp…
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.…
Charge and spin manipulation in a few-electron double dot
J. R. Petta, A. C. Johnson, J. M. Taylor +5
We demonstrate high speed manipulation of a few-electron double quantum dot. In the one-electron regime, the double dot forms a charge qubit. Microwaves are used drive transitions…
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…
Controlling a mesoscopic spin environment by quantum bit manipulation
J. M. Taylor, A. Imamoglu, M. D. Lukin
We present a unified description of cooling and manipulation of a mesoscopic bath of nuclear spins via coupling to a single quantum system of electronic spin (quantum bit). We show…
